Description

Technical Field

[0001] The present invention relates to the technical field of mineral separation, and in particular to a barite flotation method, system, electronic equipment and computer-readable storage medium based on infrared spectrum analysis and microwave. Background Art

[0002] Barite is a barium-containing mineral widely used in the petroleum, chemical, coating, plastic and other industries, especially used as a weighting agent in oil and gas drilling. Therefore, how to remove impurities (such as calcium carbonate and silicon dioxide) in barite ore and improve the purity of barite is of great significance for its application in industry.

[0003] At present, the method for purifying and removing impurities from barite ore is flotation. The main principle is to change the surface chemical properties of impurities through inhibitors to reduce the flotation activity of impurities. At the same time, the collector reacts chemically or physically adsorbs with the surface of barite particles, so that it can be preferentially adsorbed on bubbles during the flotation process and thus floated out.

[0004] Although the existing flotation method can achieve the purification and impurity removal of barite, the dosage of reagents during flotation often depends on manual experience, and the judgment of flotation results often depends on manual observation, which leads to the problem of unstable and unreliable flotation results of barite. Therefore, how to optimize the flotation process, adjust the dosage of reagents during the flotation process, and improve the purity of barite products has become an urgent problem to be solved.

[0088] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0089] The embodiment of the present application provides a barite flotation method based on infrared spectroscopy analysis of microwaves.

[0090] Reference Figure 1As shown, it is a schematic diagram of a barite flotation method based on infrared spectroscopy analysis of microwaves provided in one embodiment of the present invention. In this embodiment, the barite flotation method based on infrared spectroscopy analysis of microwaves includes:

[0091] S1. Obtain a barite ore to be selected, perform a crushing operation on the barite ore to be selected to obtain a target barite ore, use the target barite ore to obtain a collector dosage and an inhibitor dosage, obtain an initial collector based on the collector dosage, and obtain an initial inhibitor based on the inhibitor dosage.

[0092] It should be explained that the barite ore to be selected is a batch of unprocessed barite ore, wherein the barite ore is a mineral whose main component is barium sulfate. Optionally, the barite ore to be selected is obtained from a barite mining area.

[0093] For example, Xiao Zhang is a processor in a barite flotation plant. He needs to produce a batch of fine barite, so he orders a batch of unprocessed barite ore from a barite mining area as barite ore to be selected for subsequent production of fine barite. Fine barite refers to barite with a barium sulfate content greater than 95% after processing and flotation.

[0094] Importantly, the collector dosage refers to the mass of the collector required for the subsequent flotation process. The inhibitor dosage refers to the mass of the inhibitor required for the subsequent flotation process. The initial collector refers to a collector whose mass is the collector dosage. The collector is a flotation agent whose main function is to adsorb on the surface of barium sulfate in barite ore to increase the hydrophobicity of barium sulfate and make it adhere to bubbles, thereby improving the floatability of barium sulfate in barite ore. Optionally, sodium dodecyl sulfate is used as the initial collector. The initial inhibitor refers to an inhibitor whose mass is the inhibitor dosage. The inhibitor is a flotation agent whose main function is to inhibit the floatability of impurities such as calcium carbonate and silicon dioxide in barite ore. Optionally, water glass is used as the initial inhibitor.

[0095] For example, the amount of collector used is 2000 g, and Xiao Zhang extracts 2000 g of collector from the collector purchased in advance as the initial collector.

[0096] In detail, the method of performing a crushing operation on the barite ore to be selected to obtain the target barite ore includes:

[0097] Using a pre-built jaw crusher to crush the barite ore to be selected to obtain crushed barite ore, and using a pre-built ball mill to grind the crushed barite ore to obtain crushed barite ore;

[0098] Using a pre-built screen to perform screening operations on the crushed barite ore to obtain qualified barite ore and updated barite ore;

[0099] Collecting qualified barite ore into a pre-built ore collector to obtain a target collector;

[0100] Weighing the target collector and the updated barite ore respectively to obtain the collection mass and the updated mass, and confirming the qualified mass based on the collection mass;

[0101] The fine crushing ratio is calculated using the qualified quality and the updated quality, wherein the fine crushing ratio is the ratio of the qualified quality to the updated quality;

[0102] Comparing the fine crushing ratio with a preset fine crushing threshold, if the fine crushing ratio is less than the fine crushing threshold, using the updated barite ore as the crushed barite ore, and returning to the step of using the pre-built ball mill to perform a crushing operation on the crushed barite ore until the fine crushing ratio is greater than or equal to the preset fine crushing threshold;

[0103] If the fine crushing ratio is greater than or equal to the fine crushing threshold, the target collector is used to obtain the final barite ore, and the final barite ore and the updated barite ore are aggregated to obtain the target barite ore.

[0104] It should be understood that the technology of using a pre-built jaw crusher to perform a crushing operation on the barite ore to be selected and the technology of using a pre-built ball mill to perform a pulverizing operation on the crushed barite ore are both prior arts.

[0105] It should be explained that the screen is a mesh woven with metal wire or fiber wire and has a certain aperture. The crushed barite ore is the barite ore to be selected after being crushed by a jaw crusher. The crushed barite ore is the crushed barite ore after being crushed by a ball mill.

[0106] Exemplarily, the crushed barite ore is slowly poured onto the screen while the screen is vibrated at a preset frequency, the crushed barite ore passing through the screen is collected to obtain qualified barite ore, and the crushed barite ore that does not pass through the screen is collected to obtain updated barite ore.

[0107] It should be explained that the ore collector is an iron box for collecting qualified barite ore. The target collector is an ore collector that has collected qualified barite ore. The collection mass refers to the mass of the target collector. The qualified mass is determined based on the collection mass, which means: the collection mass is subtracted from the preset mass of the ore collector to obtain the qualified mass. The qualified mass represents the mass of the qualified barite ore in the target collector. The updated mass refers to the mass of the updated barite ore. The fine crushing ratio is the ratio of the qualified mass to the updated mass, which is obtained by dividing the qualified mass by the updated mass. The fine crushing threshold is related to the grinding fineness required for subsequent flotation and is set by the processor. For example, if the ideal grinding fineness of barite ore particles during flotation is 85%, the fine crushing threshold is set to 85%.

[0108] It should be understood that the use of the target collector to obtain the final barite ore means: extracting all qualified barite ores from the target collector as the final barite ore. The target barite ore consists of the final barite ore and the updated barite ore.

[0109] In detail, the method of obtaining the amount of collector and inhibitor using the target barite ore includes:

[0110] Performing a weighing operation on the target barite ore to obtain a target mass;

[0111] Use the target barite ore to obtain an ore sample, use the pre-built density meter to measure the ore sample to obtain the ore density, and use the target mass and ore density to calculate the collector dosage. The calculation formula is as follows:

[0112] ,

[0113] in, is the collector dosage, and are respectively a preset first proportional coefficient and a preset second proportional coefficient, is a natural constant, is the density of ore, is the preset density of barium sulfate, For target quality;

[0114] The inhibitor dosage is calculated using the target mass and ore density. The calculation formula is as follows:

[0115] ,

[0116] in, is the inhibitor dosage, and are respectively a preset third proportional coefficient and a preset fourth proportional coefficient, and They are respectively the preset density of silicon dioxide and the preset density of calcium carbonate.

[0117] It should be explained that the target mass refers to the mass of the target barite ore. A target barite ore of a certain mass is used as the ore sample. Ore density refers to the density of the ore sample. Optionally, a fast rock ore density tester DA-300R is used as a densitometer. The first proportional coefficient and the second proportional coefficient are related to the model and concentration of the collector and can be set by the processor. The third proportional coefficient and the fourth proportional coefficient are related to the model and concentration of the inhibitor and can be set by the processor.

[0118] S2. Obtain a sample set to be tested, and use a pre-built infrared spectrometer and the sample set to be tested to obtain a first wavenumber range, a second wavenumber range, and a third wavenumber range.

[0119] In detail, the method of obtaining the first wavenumber range, the second wavenumber range and the third wavenumber range by using a pre-built infrared spectrometer and a sample set to be tested includes:

[0120] Using an infrared spectrometer to perform infrared spectrum analysis on the sample set to be tested, to obtain a first spectrum graph, a second spectrum graph, and a third spectrum graph, wherein the sample set to be tested includes: a barium sulfate sample, a calcium carbonate sample, and a silicon dioxide sample;

[0121] A first wavenumber range is obtained using the first spectrum graph, a second wavenumber range is obtained based on the second spectrum graph, and a third wavenumber range is obtained based on the third spectrum graph.

[0122] It should be explained that the barium sulfate sample, the calcium carbonate sample and the silicon dioxide sample refer to a certain mass of high-purity barium sulfate, a certain mass of high-purity calcium carbonate and a certain mass of high-purity silicon dioxide, respectively. The infrared light band used for the infrared spectral analysis is the mid-infrared band, and the infrared spectral analysis of the sample set to be tested using an infrared spectrometer refers to the infrared spectral analysis of the barium sulfate sample, the calcium carbonate sample and the silicon dioxide sample in the sample set to be tested, respectively. The technology of performing infrared spectral analysis on the barium sulfate sample, the calcium carbonate sample and the silicon dioxide sample in the sample set to be tested, respectively, is a prior art and will not be repeated here. The first spectrogram, the second spectrogram and the third spectrogram are infrared spectral images of the barium sulfate sample, the infrared spectral images of the calcium carbonate sample and the infrared spectral images of the silicon dioxide sample, respectively.

[0123] In detail, the obtaining the first wavenumber range by using the first spectrum graph includes:

[0124] Identifying a first spectral curve in a first spectral graph, wherein the first spectral graph includes a first spectral curve in a pre-constructed first spectral coordinate system, and the horizontal axis of the first spectral coordinate system is wave number and the vertical axis is transmittance;

[0125] Identifying an initial spectrum point in the first spectrum curve, wherein the initial spectrum point is a point with the lowest transmittance in the first spectrum curve;

[0126] Using a preset transmittance threshold, a plurality of restricted spectral points are retrieved from the first spectral curve, wherein the transmittance corresponding to the restricted spectral points is equal to the transmittance threshold;

[0127] The following operations are performed for each of the multiple restricted spectral points:

[0128] If the wave number corresponding to the restricted spectrum point is greater than the wave number corresponding to the initial spectrum point, the restricted spectrum point is identified as the first spectrum point, otherwise the restricted spectrum point is identified as the second spectrum point;

[0129] Summarize the first spectral points and the second spectral points respectively to obtain a first spectral point set and a second spectral point set;

[0130] The following operations are performed on the first spectral point in the first spectral point set:

[0131] Calculate the absolute difference between the wavenumber corresponding to the first spectral point and the wavenumber corresponding to the initial spectral point to obtain an evaluation wavenumber difference, summarize the evaluation wavenumber differences to obtain an evaluation wavenumber difference set, and confirm the first spectral range point based on the evaluation wavenumber difference set, wherein the first spectral range point is the first spectral point corresponding to the smallest evaluation wavenumber difference in the evaluation wavenumber difference set;

[0132] A second spectral range point is obtained based on a second spectral point set, and a first wavenumber range is obtained using the first spectral range point and the second spectral range point, wherein the wavenumber corresponding to the first spectral range point and the wavenumber corresponding to the second spectral range point are respectively the maximum value and the minimum value of the first wavenumber range.

[0133] It should be explained that the first spectral coordinate system is the coordinate system of the infrared spectrum in the first spectrogram, and the first spectral curve is the curve on the infrared spectrum in the first spectrogram, which reflects the transition of vibration energy levels and rotation energy levels generated by the barium sulfate sample absorbing light of a specific frequency under mid-infrared light irradiation.

[0134] Reference Figure 2 , which is a schematic diagram of a first spectrum diagram of a barite flotation method based on infrared spectrum analysis microwaves provided by an embodiment of the present invention.

[0135] It is understandable that the transmittance threshold is related to the molecular properties of barium sulfate and can be set by the processor. The limiting spectral point is the point in the first spectral curve where the transmittance is equal to the transmittance threshold. The first spectral point and the second spectral point are respectively the limiting spectral point whose wavenumber is greater than the wavenumber corresponding to the initial spectral point and the limiting spectral point whose wavenumber is less than the wavenumber corresponding to the initial spectral point. It should be understood that the method of obtaining the second spectral range point based on the second spectral point set is the same as the method of obtaining the first spectral range point using the first spectral point set, which will not be repeated here. The method of obtaining the second wavenumber range based on the second spectral graph and the method of obtaining the third wavenumber range based on the third spectral graph are both the same as the method of obtaining the first wavenumber range using the first spectral graph, which will not be repeated here.

[0136] It should be explained that the first wave number range is as follows:

[0137] ,

[0138] in, is the wave number corresponding to the point in the second spectral range, is the wave number corresponding to the point in the first spectral range.

[0139] It can be understood that since the first spectrum graph is an infrared spectrum image of the barium sulfate sample and the initial spectrum point is the point with the lowest transmittance in the first spectrum curve, the wavenumber corresponding to the initial spectrum point is the infrared light wavenumber with the highest absorption rate of the barium sulfate molecule. Therefore, the area corresponding to the first wavenumber range obtained using the infrared light wavenumber in the first spectrum curve can approximately represent the characteristic peak of the sulfur-oxygen bond in the barium sulfate molecule. Similarly, the area corresponding to the second wavenumber range in the second spectrum curve can approximately represent the characteristic peak of the carbonate ion in calcium carbonate, and the area corresponding to the third wavenumber range in the third spectrum curve can approximately represent the characteristic peak of the silicon-oxygen bond in the silicon dioxide molecule.

[0140] S3. placing the target barite ore, the initial collector and the initial inhibitor into a pre-constructed first flotation cell to obtain a primary flotation cell, obtaining a flotation mixture based on the primary flotation cell, performing a flotation operation on the flotation mixture using the primary flotation cell to obtain a flotation froth, extracting a flotation sample from the flotation froth, and performing an infrared spectroscopy analysis on the flotation sample using an infrared spectrometer to obtain a flotation spectrum graph.

[0141] It should be explained that the first flotation cell is a tank container used for flotation. The primary flotation cell is the first flotation cell into which the target barite ore, the initial collector and the initial depressant are placed.

[0142] It should be understood that the flotation mixture obtained based on the primary flotation cell refers to: adding a pre-constructed frother and a pre-constructed dispersant to the target flotation cell, and adding a preset volume of deionized water for mixing to obtain a flotation mixture. Optionally, pine oil is used as a frother, sodium hexametaphosphate is used as a dispersant, and the volume of the frother, the volume of the dispersant and the volume of the deionized water added are related to the volume of the flotation cell, the concentration of the frother and the concentration of the dispersant, and can be set by the processor.

[0143] It is understandable that the technology of performing flotation operation on the flotation mixture using the primary flotation cell is a prior art and will not be described in detail here. The flotation foam is the foam that is scraped out or overflowed when the flotation mixture is flotated in the primary flotation cell and contains the target barite ore. Extracting the flotation sample from the flotation foam means: extracting a certain mass of flotation foam as the flotation sample. The technology of performing infrared spectroscopy analysis on the flotation sample using an infrared spectrometer is a prior art and will not be described in detail here.

[0144] S4. Calculate the first spectrum peak intensity, the second spectrum peak intensity and the third spectrum peak intensity by using the flotation spectrum graph, the first wave number range, the second wave number range and the third wave number range.

[0145] In detail, the method of calculating the first spectrum peak intensity, the second spectrum peak intensity and the third spectrum peak intensity by using the flotation spectrum graph, the first wave number range, the second wave number range and the third wave number range includes:

[0146] Identifying a flotation spectrum curve in a flotation spectrum graph, wherein the flotation spectrum graph includes a flotation spectrum curve in a pre-constructed flotation spectrum coordinate system, wherein the horizontal axis of the flotation spectrum coordinate system is wave number and the vertical axis is transmittance;

[0147] Using the preset sampling interval, a uniform sampling operation is performed on the first wave number range to obtain n reference wave number values, and the following operation is performed on each of the n reference wave number values:

[0148] Using the reference wave value, a reference spectrum point is retrieved from the flotation spectrum curve, wherein the wave number corresponding to the reference spectrum point is equal to the reference wave value;

[0149] Summarize the reference spectrum points to obtain n reference spectrum points, and sort the n reference spectrum points in ascending order of the wave numbers corresponding to the reference spectrum points to obtain a reference point sequence;

[0150] The first spectrum peak intensity is calculated using the reference point sequence. The calculation formula is as follows:

[0151] ,

[0152] in, is the first peak intensity, and are the first The wave number and transmittance corresponding to each reference spectral point, and are the first The wave number and transmittance corresponding to each reference spectral point, is the transmittance threshold;

[0153] The second spectral peak intensity is obtained based on the second wavenumber range and the flotation spectrum, and the third spectral peak intensity is obtained based on the third wavenumber range and the flotation spectrum.

[0154] It should be explained that the flotation spectrum coordinate system is the coordinate system of the infrared spectrum in the flotation spectrum diagram, and the flotation spectrum curve is the curve on the infrared spectrum in the flotation spectrum diagram, which reflects the transition of vibration energy levels and rotation energy levels generated by the flotation sample absorbing light of a specific frequency under the irradiation of mid-infrared light.

[0155] Exemplarily, the first wave number range is , if the sampling interval of uniform sampling is , then we get 3 reference wave values: , , , if the sampling interval of uniform sampling is , then 11 reference wave values ​​are obtained: , … , and the sampling interval can be set by the processor.

[0156] It should be explained that the reference spectrum point is a point in the flotation spectrum curve whose wave number is equal to the reference wave value. The method of obtaining the second spectrum peak intensity based on the second wave number range and the flotation spectrum graph and the method of obtaining the third spectrum peak intensity based on the third wave number range and the flotation spectrum graph are the same as the method of obtaining the first spectrum peak intensity using the first wave number range and the flotation spectrum graph, which will not be repeated here.

[0157] It should be understood that the area corresponding to the first wave number range in the flotation spectrum curve approximately represents the characteristic peak of the sulfur-oxygen bond in the barium sulfate molecule. Therefore, the first spectrum peak intensity calculated by the first wave number range reflects the content of barium sulfate in the flotation sample. The higher the first spectrum peak intensity, the higher the content of barium sulfate in the flotation sample. Similarly, the second spectrum peak intensity and the third spectrum peak intensity respectively reflect the contents of calcium carbonate and silicon dioxide in the flotation sample.

[0158] S5. Compare the second spectrum peak intensity with a preset second intensity threshold and compare the third spectrum peak intensity with a preset third intensity threshold.

[0159] It should be explained that the second intensity threshold and the third intensity threshold are related to the physical properties of the fine barite ore and are set by the processor.

[0160] Exemplarily, the fine barite ore historically produced by the barite flotation plant is sampled to obtain an ideal sample, the ideal sample is subjected to infrared spectroscopy to obtain an ideal spectrum graph, and the spectral peak intensity corresponding to the ideal spectrum graph in the second wavenumber range is calculated as the second intensity threshold. The method for obtaining the third intensity threshold is the same as the method for obtaining the second intensity threshold, which will not be repeated here.

[0161] S6. If the second spectrum peak intensity is less than or equal to the second intensity threshold and the third spectrum peak intensity is less than or equal to the third intensity threshold, the first spectrum peak intensity is recorded as the target spectrum peak intensity and the flotation foam is recorded as the target foam.

[0162] It should be understood that since the second spectral peak intensity and the third spectral peak intensity respectively reflect the calcium carbonate content and the silica content in the flotation sample, when the second spectral peak intensity is less than or equal to the second intensity threshold and the third spectral peak intensity is less than or equal to the third intensity threshold, it means that the calcium carbonate content and the silica content in the flotation foam corresponding to the flotation sample are small enough, and there is no need to add inhibitors again for flotation to remove calcium carbonate and silica. The flotation foam can be used as the target foam for subsequent flotation in the second flotation tank, and the first spectral peak intensity can be recorded as the target spectral peak intensity for the subsequent calculation of the barite percentage.

[0163] S7. If the second spectral peak intensity is greater than the second intensity threshold or the third spectral peak intensity is greater than the third intensity threshold, the inhibitor addition amount is calculated using the flotation sample, the second spectral peak intensity, the second intensity threshold, the third spectral peak intensity, the third intensity threshold and the inhibitor dosage.

[0164] In detail, the method of calculating the inhibitor addition amount using the flotation sample, the second spectrum peak intensity, the second intensity threshold, the third spectrum peak intensity, the third intensity threshold and the inhibitor dosage includes:

[0165] Respectively measure the pH value and temperature of the flotation sample to obtain the flotation pH value and flotation temperature value;

[0166] The inhibitor addition amount is calculated based on the second spectrum peak intensity, the second intensity threshold, the third spectrum peak intensity, the third intensity threshold, the inhibitor dosage, the flotation pH value and the flotation temperature value. The calculation formula is as follows:

[0167] ,

[0168] in, is the inhibitor addition amount, is the flotation pH value, is the flotation temperature, is the preset environmental factor, is the second intensity threshold, is the third intensity threshold, is the second peak intensity, is the third peak intensity.

[0169] It should be explained that the flotation pH value is the pH value of the flotation sample, and the flotation temperature value is the temperature value of the flotation sample. The techniques for measuring the pH value and temperature of the flotation sample are all prior arts and will not be described here. The environmental coefficient is the temperature of pure water in the current environment multiplied by the pH value of pure water. The amount of inhibitor added refers to the mass of the inhibitor that needs to be added in the subsequent flotation process.

[0170] S8. Obtain an updated inhibitor based on the amount of inhibitor added, return the flotation foam to the primary flotation cell to obtain an updated flotation cell, obtain an updated mixed liquor based on the updated flotation cell, and obtain updated foam and updated spectrum peak intensity using the updated mixed liquor, the updated inhibitor and the updated flotation cell.

[0171] In detail, the method of obtaining the updated foam and the updated spectrum peak intensity by using the updated mixed solution, the updated inhibitor and the updated flotation cell includes:

[0172] adding a renewal inhibitor to the renewal mixed solution in the renewal flotation tank to obtain an inhibited mixed solution, and performing a flotation operation on the inhibited mixed solution using the renewal flotation tank to obtain a renewal foam;

[0173] Extracting a renewal sample from the renewal foam, performing infrared spectrum analysis on the renewal sample using an infrared spectrometer to obtain a renewal spectrum graph;

[0174] An updated spectrum peak intensity is obtained based on the updated spectrum graph and the first wavenumber range.

[0175] It should be explained that the renewal inhibitor refers to an inhibitor whose mass is the amount of inhibitor added. The renewal flotation cell refers to a primary flotation cell that returns the flotation foam. The obtaining of the renewal mixed solution based on the renewal flotation cell refers to: mixing the flotation foam with the flotation mixed solution in the renewal flotation cell to obtain the renewal mixed solution. The inhibition mixed solution is the renewal mixed solution to which the renewal inhibitor is added. The renewal foam is the foam that is scraped out or overflowed when the inhibition mixed solution is floated in the renewal flotation cell and contains the target barite ore.

[0176] It should be understood that the technology of using the updated flotation tank to perform flotation operation on the suppressed mixed solution and the technology of using the infrared spectrometer to perform infrared spectrum analysis on the updated sample are both existing technologies and will not be described in detail here. The updated spectrum diagram is an infrared spectrum diagram of the updated sample.

[0177] It is understandable that the method of obtaining the updated spectral peak intensity based on the updated spectrum and the first wavenumber range is the same as the method of obtaining the first spectral peak intensity using the flotation spectrum and the first wavenumber range, which will not be repeated here.

[0178] S9, introducing the target foam or the updated foam into the pre-constructed second flotation cell to obtain the target flotation cell, confirming the final flotation foam in the target flotation cell based on the target spectrum peak intensity or the updated spectrum peak intensity, and using the final flotation foam to obtain fine barite to complete the flotation of barite.

[0179] It should be explained that the second flotation cell is a tank container used for flotation. The target flotation cell is a second flotation cell into which the target froth or renewed froth is introduced.

[0180] It should be understood that the method of obtaining fine barite by using the final flotation foam means filtering the final flotation foam, separating the barite particles in the foam, and washing and drying the barite particles to obtain fine barite. The techniques of filtering the final flotation foam and washing and drying the barite particles are both prior arts and will not be described in detail here.

[0181] In detail, the step of confirming the final flotation froth in the target flotation cell based on the target spectrum peak intensity or the updated spectrum peak intensity includes:

[0182] The barite percentage is calculated using the target peak intensity or updated peak intensity. The calculation formula is as follows:

[0183] ,

[0184] in, is the barite percentage, is the target peak intensity or updated peak intensity, is a preset first intensity threshold;

[0185] comparing the barite percentage with a preset percentage threshold, and if the barite percentage is greater than or equal to the percentage threshold, taking the flotation froth or the renewed froth as the final flotation froth;

[0186] If the barite percentage is less than the percentage threshold, the precise dosage is calculated based on the collector dosage, barite percentage and percentage threshold, and the calculation formula is as follows:

[0187] ,

[0188] in, For precise dosage, is the percentage threshold;

[0189] Obtaining a precision collector based on a precise dosage, introducing the precision collector into a target flotation cell to obtain a precision flotation cell, and obtaining a precision mixed solution based on the precision flotation cell;

[0190] A pre-constructed pH regulator is added to a precision mixed liquid based on a preset adjustment frequency to obtain an adjusted mixed liquid, a flotation operation is performed on the adjusted mixed liquid using a precision flotation tank to obtain a real-time mixed liquid, a precision sample is extracted from the real-time mixed liquid according to the adjustment frequency, and an infrared spectrometer is used to perform infrared spectroscopy analysis on the precision sample to obtain a precision spectrum graph;

[0191] The precise spectrum peak intensity is obtained based on the precise spectrum graph and the first wave number range, and the barite percentage is calculated based on the precise spectrum peak intensity. When the barite percentage is greater than or equal to the percentage threshold, the precise foam is extracted from the real-time mixed liquid and used as the final flotation foam.

[0192] It should be explained that the barite percentage reflects the content of barium sulfate in the mineral particles wrapped in the final flotation foam. The higher the barite percentage, the higher the barium sulfate content. The first intensity threshold and the percentage threshold are related to the barium sulfate content in the fine barite under ideal conditions and can be set by the processor. The precision dosage refers to the mass of the collector that needs to be added in the subsequent flotation process. The precision collector refers to the collector with a mass of the precision dosage. The precision flotation cell is the target flotation cell into which the precision collector is introduced.

[0193] It should be understood that the method for obtaining a precision mixed solution based on the precision flotation cell is the same as the method for obtaining a flotation mixed solution using the primary flotation cell, and will not be described in detail herein.

[0194] It should be explained that the pH regulator is a kind of agent that can adjust the pH value of the precision mixed solution. Optionally, sodium carbonate is used as the pH regulator. The adjustment frequency is related to the model and concentration of the pH regulator and can be set by the processor. The technology of using a precision flotation tank to perform flotation operations on the adjusted mixed solution and the technology of using an infrared spectrometer to perform infrared spectroscopy analysis on precision samples are both existing technologies and will not be repeated here. The final flotation foam refers to the precision foam or flotation foam when the barite percentage is greater than or equal to the percentage threshold.

[0195] Exemplarily, the time interval corresponding to the adjustment frequency is 20 minutes. At 10:00, a certain volume of pH adjuster is added to the precision mixed liquid to obtain an adjusted mixed liquid, and the adjusted mixed liquid is floated. The adjusted mixed liquid in the flotation process is used as the real-time mixed liquid. At the same time, a certain mass of foam is extracted from the surface of the real-time mixed liquid as a precision sample, and then an infrared spectrometer is used to perform infrared spectroscopy analysis on the precision sample. At 10:20, the above process is repeated until the barite percentage is greater than or equal to the percentage threshold, and all the foam is scraped off from the surface of the real-time mixed liquid as precision foam.

[0196] The present invention solves the problem described in the background technology. The present invention obtains a barite ore to be selected, performs a crushing operation on the barite ore to be selected, obtains a target barite ore, uses the target barite ore to obtain a collector dosage and an inhibitor dosage, obtains an initial collector based on the collector dosage, and obtains an initial inhibitor based on the inhibitor dosage. It can be seen that the embodiment of the present invention increases the surface area of ​​the target barite ore by crushing the barite ore to be selected, and improves the contact area between the collector and the inhibitor and the target barite ore particles in the subsequent flotation process, thereby improving the flotation speed. At the same time, the appropriate amount of collector and inhibitor is determined according to the target barite ore, thereby improving the stability of the subsequent flotation process, and then, a sample set to be tested is obtained, and a pre-built infrared spectrometer and a sample set to be tested are used to obtain Taking the first wavenumber range, the second wavenumber range and the third wavenumber range, it can be seen that the embodiment of the present invention determines the wavenumber ranges corresponding to the barium sulfate molecules, the calcium carbonate molecules and the silicon dioxide molecules by performing infrared spectroscopy analysis on the sample set to be tested in advance, so as to facilitate the subsequent use of the wavenumber range to analyze the flotation spectrum, and the target barite ore, the initial collector and the initial inhibitor are placed in a pre-constructed first flotation cell to obtain a primary flotation cell, and a flotation mixture is obtained based on the primary flotation cell, and a flotation operation is performed on the flotation mixture using the primary flotation cell to obtain a flotation foam, and a flotation sample is extracted from the flotation foam, and an infrared spectrometer is used to perform infrared spectroscopy analysis on the flotation sample to obtain a flotation spectrum. It can be seen that the embodiment of the present invention analyzes the barite ore by an infrared spectrometer to monitor the barite The composition changes of the stone ore can be avoided, the errors caused by manual judgment can be avoided, thereby providing a scientific basis for the flotation process and improving the accuracy of flotation. The first spectral peak intensity, the second spectral peak intensity and the third spectral peak intensity are calculated by using the flotation spectrum, the first wavenumber range, the second wavenumber range and the third wavenumber range. It can be seen that the embodiment of the present invention quantifies the content of different components in the barite ore by calculating the first spectral peak intensity, the second spectral peak intensity and the third spectral peak intensity, which lays a foundation for the subsequent adjustment of the collector or inhibitor according to the impurity content. The second spectral peak intensity is compared with the preset second intensity threshold and the third spectral peak intensity is compared with the preset third intensity threshold. If the second spectral peak intensity is less than or equal to the second intensity threshold and the third spectral peak intensity is less than or equal to the third intensity threshold, the first spectral peak intensity is increased. The intensity is recorded as the target spectral peak intensity, and the flotation foam is taken as the target foam. It can be seen that the embodiment of the present invention ensures that the flotation result meets the expected standard by comparing the spectral peak intensity with the preset intensity threshold, thereby improving the stability of the flotation result. If the second spectral peak intensity is greater than the second intensity threshold or the third spectral peak intensity is greater than the third intensity threshold, the flotation sample, the second spectral peak intensity, the second intensity threshold, the third spectral peak intensity, the third intensity threshold and the inhibitor dosage are used to calculate the inhibitor addition amount. It can be seen that the embodiment of the present invention ensures that the inhibitory effect on impurities in the flotation process is more stable and efficient by accurately calculating the inhibitor addition amount, obtains an updated inhibitor based on the inhibitor addition amount, returns the flotation foam to the primary flotation cell to obtain an updated flotation cell, and obtains an updated mixed solution based on the updated flotation cell.By updating the mixed solution, updating the inhibitor and updating the flotation cell to obtain the updated foam and updated spectral peak intensity, it can be seen that the embodiment of the present invention reduces the waste of reagents and improves the recovery rate of barite ore by returning the flotation foam and further flotation after adding the inhibitor. The target foam or the updated foam is introduced into the pre-constructed second flotation cell to obtain the target flotation cell. The final flotation foam is confirmed in the target flotation cell based on the target spectral peak intensity or the updated spectral peak intensity. The final flotation foam is used to obtain fine barite to complete the flotation of barite. It can be seen that the embodiment of the present invention dynamically monitors the final flotation process through an infrared spectrometer to ensure that high-purity fine barite is obtained, thereby improving the purity of the barite product. Therefore, the present invention can optimize the flotation process and improve the purity and recovery rate of the barite product. ,

[0197] like Figure 3 , which is a functional module diagram of a barite flotation system based on infrared spectroscopy analysis and microwaves provided in one embodiment of the present invention.

[0198] The barite flotation system 100 based on infrared spectrum analysis microwaves of the present invention can be installed in an electronic device.

The module of the present invention can also be referred to as a unit, which refers to a series of computer program segments that can be executed by an electronic device processor and can complete fixed functions, which are stored in the memory of the electronic device.

[0201] The reagent dosage adjustment module 103 is used to compare the second spectrum peak intensity with a preset second intensity threshold and to compare the third spectrum peak intensity with a preset third intensity threshold. If the second spectrum peak intensity is less than or equal to the second intensity threshold and the third spectrum peak intensity is less than or equal to the third intensity threshold, the first spectrum peak intensity is recorded as the target spectrum peak intensity and the flotation foam is taken as the target foam. If the second spectrum peak intensity is greater than the second intensity threshold or the third spectrum peak intensity is greater than the third intensity threshold, the inhibitor addition amount is calculated using the flotation sample, the second spectrum peak intensity, the second intensity threshold, the third spectrum peak intensity, the third intensity threshold and the inhibitor dosage, an updated inhibitor is obtained based on the inhibitor addition amount, the flotation foam is returned to the primary flotation cell to obtain an updated flotation cell, an updated mixed solution is obtained based on the updated flotation cell, and updated foam and updated spectrum peak intensity are obtained using the updated mixed solution, the updated inhibitor and the updated flotation cell;

[0202] The fine barite flotation module 104 is used to introduce the target foam or the updated foam into the pre-constructed second flotation cell to obtain the target flotation cell, confirm the final flotation foam in the target flotation cell based on the target spectrum peak intensity or the updated spectrum peak intensity, and use the final flotation foam to obtain fine barite to complete the flotation of barite.

[0203] In detail, the modules in the barite flotation system 100 based on infrared spectroscopy analysis microwaves in the embodiment of the present invention are used in the same manner as described above. Figure 1 The barite flotation method based on infrared spectroscopy analysis and microwaves described in the text is the same technical means and can produce the same technical effects, so I will not go into details here.
