Description

Technical Field

[0001] This invention relates to the field of vanadium slag iron removal, specifically to a control method, device, equipment, and medium for avoiding vanadium slag loss during vanadium slag iron selection. Background Technology

[0002] Currently, the main process for producing vanadium pentoxide is the indirect vanadium extraction method using vanadium slag as raw material. After grinding and iron selection, sodium salt additives are added to the vanadium slag in a proportional manner, followed by sodium roasting in a rotary kiln. This converts insoluble vanadium compounds into soluble sodium vanadate, which is then leached in water to form a sodium vanadate solution. After purification and phosphorus removal, sulfuric acid and ammonium sulfate are added, and ammonium salt precipitation occurs under heating conditions to produce ammonium polyvanadate. The ammonium polyvanadate is then decomposed, melted, and cast into flake vanadium pentoxide.

[0003] For example, CN101215005A discloses a method for producing vanadium pentoxide from vanadium slag. The method includes the following steps: a) adding alkali metal salts to vanadium slag and mixing thoroughly to obtain a mixture; b) placing the mixture obtained in step a) in a roasting furnace for oxidative roasting to obtain vanadium slag clinker; c) removing the roasted vanadium slag clinker from the furnace, rapidly cooling it, and immersing it in water; d) filtering the mixture obtained in step c) to obtain a filtrate; e) removing impurities from the filtrate; f) adjusting the pH value of the filtrate obtained in step e), adding ammonium salts to precipitate vanadium, and filtering to obtain ammonium polyvanadate or ammonium metavanadate filter cake; g) calcining the precipitated vanadium filter cake obtained in step f) to obtain vanadium pentoxide.

[0004] CN118929751A A method for preparing vanadium pentoxide using high-chromium vanadium slag. The method includes the following steps: (1) crushing the high-chromium vanadium slag and then performing magnetic separation to remove iron, grinding and air separation to remove impurities to obtain refined vanadium slag; (2) mixing sodium salt and the refined vanadium slag obtained in step (1), and then roasting it in a rotary kiln to obtain clinker; (3) wet grinding the clinker obtained in step (2), and then post-processing to obtain the vanadium pentoxide.

[0005] However, current methods for iron beneficiation using vanadium slag have the drawback of carrying a large amount of vanadium slag in the iron product. Although existing methods can effectively ensure the iron beneficiation effect of vanadium slag, it is unavoidable that the iron product will carry too much vanadium slag during the iron beneficiation process. Taking away too much vanadium slag will increase vanadium loss and cause economic losses. However, there is currently no effective method to monitor the vanadium slag content of the iron product from vanadium slag iron beneficiation. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a control method, device, equipment and medium for avoiding vanadium slag loss in vanadium slag iron beneficiation, so as to achieve effective monitoring of the vanadium slag content of the iron product obtained from vanadium slag iron beneficiation, thereby solving the defect that the vanadium slag content of the iron product obtained from vanadium slag iron beneficiation cannot be reasonably monitored, resulting in a high vanadium slag loss rate.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] In a first aspect, the present invention provides a method for controlling the loss of vanadium slag in the iron ore beneficiation of vanadium slag, the method comprising:

[0009] The first sample is obtained from the iron product obtained by crushing and beneficiating vanadium slag in the iron beneficiation of vanadium slag, and the first vanadium slag content of the first sample is obtained.

[0011] A third sample was obtained from the iron product obtained by wind separation of vanadium slag in iron beneficiation, and the vanadium slag content of the third sample was obtained.

[0012] The total slag content of iron was obtained based on the contents of the first vanadium slag, the second vanadium slag, and the third vanadium slag.

[0013] If the total slag content of iron is >30%, adjust the vanadium slag iron beneficiation process until the total slag content of iron is ≤30%; otherwise, maintain the process.

[0014] The control method provided by this invention achieves effective monitoring of the vanadium slag content in the product by designing a reasonable detection process, thereby avoiding excessive loss of vanadium slag during iron selection and ensuring efficient utilization of vanadium in the vanadium slag.

[0015] As a preferred technical solution of the present invention, the first sample is obtained by a five-point sampling method.

[0016] As a preferred technical solution of the present invention, the process of obtaining the content of the first vanadium slag is as follows:

[0017] The first sample was crushed to a particle size ≤ A1, and then slag and iron were separated to obtain the first iron and the first sub-sample.

[0019] The second sub-sample was ground to a particle size ≤ A3, and then slag and iron were separated to obtain the third iron and the third sub-sample.

[0020] The content of the first vanadium slag is calculated as (mass of the third subsample / mass of the first sample) × 100%.

[0034] Preferably, the mesh size of the sieve used in the second screening is 110-130 mesh.

[0035] As a preferred technical solution of the present invention, the formula for calculating the total slag content of iron is as follows:

[0036] Total slag content of iron = {[M1 / (M1+M2+M3)]×V1}+{[M2 / (M1+M2+M3)]×V2}+{[M3 / (M1+M2+M3)]×V3}, where M1 is the mass of iron product obtained from crushing and beneficiation, g; M2 is the mass of iron product obtained from ball milling and beneficiation, g; M3 is the mass of iron product obtained from air classification and iron removal, g; V1 is the content of the first vanadium slag, %; V2 is the content of the second vanadium slag, %; V3 is the content of the third vanadium slag, %.

[0052] The present invention will now be described in further detail. However, the examples described below are merely simplified examples of the present invention and do not represent or limit the scope of protection of the present invention. The scope of protection of the present invention is determined by the claims. Detailed Implementation

[0053] To better illustrate the present invention and facilitate understanding of its technical solutions, typical but non-limiting embodiments of the present invention are as follows:

[0054] Currently, when preparing vanadium pentoxide from vanadium slag, it is usually necessary to remove the iron from the vanadium slag. However, the iron removal process often results in the loss of vanadium slag, leading to reduced economic benefits. Currently, there are no effective monitoring methods to monitor the vanadium slag content in iron products to ensure that the loss of vanadium slag is minimized. Therefore, this invention improves the utilization rate of vanadium slag by effectively detecting the vanadium slag content in iron products, as detailed below:

[0055] I. This embodiment provides a method for controlling vanadium slag loss during vanadium slag iron ore beneficiation, such as... Figure 1 As shown, the control method includes:

[0056] The first sample is obtained from the iron product obtained by crushing and beneficiating vanadium slag in the iron beneficiation of vanadium slag, and the first vanadium slag content of the first sample is obtained.

[0057] A second sample was obtained from the iron product obtained by ball milling iron from vanadium slag beneficiation, and the second vanadium slag content of the second sample was obtained.

[0058] A third sample was obtained from the iron product obtained by wind separation of vanadium slag in iron beneficiation, and the vanadium slag content of the third sample was obtained.

[0059] The total slag content of iron was obtained based on the contents of the first vanadium slag, the second vanadium slag, and the third vanadium slag.

[0060] If the total slag content of iron is >30%, adjust the vanadium slag iron beneficiation process until the total slag content of iron is ≤30%; otherwise, maintain the process.

[0061] In this invention, the iron removal process from vanadium slag refers to the mixing operations such as crushing, grinding, air separation, and magnetic separation of vanadium slag to remove iron from the vanadium slag.

[0062] In this invention, adjusting the vanadium slag iron beneficiation process to a total slag content of ≤30% means adjusting relevant process parameters in the vanadium slag iron beneficiation process, such as crushing ratio, grinding ratio, magnetic separation parameters such as magnetic field strength, and feeding speed, so that the total slag content in the iron product is ≤30%.

[0063] In this invention, iron selection through crushing refers to the process of selecting iron after crushing. This process can be performed once or multiple times consecutively, depending on actual needs. However, it is necessary to ensure that samples are obtained after iron selection through crushing. If only crushing is performed, no samples are obtained. If the first crushing, the second crushing, and iron selection are performed sequentially, samples are obtained after iron selection.

[0064] In this invention, if there are multiple crushing and iron selection processes, the first sample includes multiple samples obtained after multiple crushing and iron selection processes, and the corresponding first vanadium slag content needs to be obtained for each sample.

[0065] In this invention, ball milling for iron selection refers to selecting iron after ball milling. Specifically, it can be done once or multiple times in succession, depending on actual needs. However, it is necessary to ensure that the sample is obtained after ball milling for iron selection. If only ball milling is performed, no sample is obtained. If the first ball milling, the second ball milling, and iron selection are performed in sequence, the sample is obtained after iron selection.

[0066] In this invention, if there are multiple ball milling processes for iron selection, the second sample includes multiple samples obtained after multiple ball milling processes for iron selection, and the corresponding second vanadium slag content needs to be obtained for each sample.

[0067] In this invention, air separation for iron removal refers to the process of separating iron after air separation. Specifically, it can be done once or multiple times in succession, depending on actual needs. However, it is necessary to ensure that samples are obtained after air separation of iron. If only air separation is performed, no samples are obtained. If the first air separation, the second air separation, and iron separation are performed in sequence, samples are obtained after iron separation.

[0068] In this invention, if there are multiple air classifications for iron removal, the third sample includes multiple samples obtained after multiple air classifications for iron removal, and the corresponding third vanadium slag content needs to be obtained for each sample.

[0069] The first sample was obtained using a five-point sampling method.

[0070] The process for obtaining the content of the first vanadium slag is as follows:

[0071] The first sample was crushed to a particle size ≤ A1, and then slag and iron were separated to obtain the first iron and the first sub-sample.

[0072] The first sub-sample was crushed to a particle size ≤ A2, and then slag and iron were separated to obtain the second iron and the second sub-sample.

[0073] The second sub-sample was ground to a particle size ≤ A3, and then slag and iron were separated to obtain the third iron and the third sub-sample.

[0074] The content of the first vanadium slag is calculated as (mass of the third subsample / mass of the first sample) × 100%.

[0075] Wherein, A1 is a point value selected from 100-110mm, such as 100mm, 101mm, 102mm, 103mm, 104mm, 105mm, 106mm, 107mm, 108mm, 109mm or 110mm, but is not limited to the listed values. Other unlisted values ​​within this range also meet the requirements.

[0076] Wherein, A2 is a point value selected from 35-40mm, such as 35mm, 35.5mm, 36mm, 36.5mm, 37mm, 37.5mm, 38mm, 38.5mm, 39mm, 39.5mm or 40mm, but is not limited to the listed values. Other unlisted values ​​within this range also meet the requirements.

[0077] Wherein, A3 is a point value selected from 0.1-0.15mm, such as 0.1mm, 0.105mm, 0.11mm, 0.115mm, 0.12mm, 0.125mm, 0.13mm, 0.135mm, 0.14mm, 0.145mm or 0.15mm, but is not limited to the listed values. Other unlisted values ​​within this range also meet the requirements.

[0078] The slag-iron separation method includes: strong magnetic separation.

[0079] The feeding rate in the slag-iron separation process is 40-60 t / h, for example, it can be 40 t / h, 42 t / h, 44 t / h, 46 t / h, 48 t / h, 50 t / h, 52 t / h, 54 t / h, 56 t / h, 58 t / h or 60 t / h, but is not limited to the listed values. Other unlisted values ​​within this range also meet the requirements.

[0080] The acquisition of the second vanadium slag content includes: the second sample undergoing a first sieve to obtain a first sieve oversize sample and a first sieve undersize sample;

[0081] The content of the second vanadium slag is calculated as follows: (mass of the first sieve sample / mass of the second sample) × 100%.

[0082] The mesh size of the sieve used in the first screening is 110-130 mesh, for example, it can be 110 mesh, 112 mesh, 114 mesh, 116 mesh, 118 mesh, 120 mesh, 122 mesh, 124 mesh, 126 mesh, 128 mesh or 130 mesh, etc., but is not limited to the listed values. Other unlisted values ​​within this range also meet the requirements.

[0083] The acquisition of the third vanadium slag content includes: performing a second sieve on the third sample to obtain a second sieve upper sample and a second sieve lower sample;

[0084] The second sieved sample is subjected to slag-iron separation to obtain the third sample iron and the third sample slag.

[0085] The content of the third vanadium slag is calculated as follows: (mass of the third sample slag / mass of the third sample) × 100%.

[0086] The mesh size of the sieve used in the second screening is 110-130 mesh, for example, it can be 110 mesh, 112 mesh, 114 mesh, 116 mesh, 118 mesh, 120 mesh, 122 mesh, 124 mesh, 126 mesh, 128 mesh or 130 mesh, but is not limited to the listed values. Other unlisted values ​​within this range also meet the requirements.

[0087] The formula for calculating the total slag content of the iron is as follows:

[0088] Total slag content of iron = {[M1 / (M1+M2+M3)]×V1}+{[M2 / (M1+M2+M3)]×V2}+{[M3 / (M1+M2+M3)]×V3}, where M1 is the mass of iron product obtained from crushing and beneficiation, g; M2 is the mass of iron product obtained from ball milling and beneficiation, g; M3 is the mass of iron product obtained from air classification and iron removal, g; V1 is the content of the first vanadium slag, %; V2 is the content of the second vanadium slag, %; V3 is the content of the third vanadium slag, %.

[0089] If the first sample includes multiple iron ore crushing and beneficiation processes, it is considered as a single sample for calculation. For example, if iron ore crushing and beneficiation are performed twice, the first sample includes two iron ore crushing and beneficiation samples. The formula for calculating the total slag content of iron is as follows:

[0090] Total slag content of iron = {[M 11 / (M 11 +M 12 +M2+M3)]×V 11}+{[M 12 / (M 11 +M 12 +M2+M3)]×V 12}+{[M2 / (M 11 +M 12+M2+M3)]×V2}+{[M3 / (M 11 +M 12 +M2+M3)]×V3};

[0091] In the formula, M 11 For the first crushing and beneficiation of iron to obtain the iron product, g; M 12 M1 represents the mass of iron product obtained from the second crushing and iron separation process, in g; M2 represents the mass of iron product obtained from ball milling and iron separation, in g; M3 represents the mass of iron product obtained from air classification and iron removal, in g; V 11 To obtain the vanadium slag content of the iron product sample from the first crushing and beneficiation, %; V 12 The process for obtaining the vanadium slag content of the iron product sample in the second crushing and iron beneficiation step is as follows: V2 is the second vanadium slag content, V3 is the third vanadium slag content, and so on.

[0092] II. This embodiment provides a control device for preventing vanadium slag loss in vanadium slag iron ore beneficiation, such as... Figure 2 As shown, the control device includes:

[0093] The first acquisition module 100 is used to acquire a first sample from the iron products obtained by crushing and beneficiating vanadium slag in vanadium slag iron beneficiation, and to acquire the first vanadium slag content of the first sample.

[0094] The second acquisition module 200 is used to acquire a second sample from the iron product obtained by ball milling iron from vanadium slag iron beneficiation, and to acquire the second vanadium slag content of the second sample;

[0096] The control module 400 is used to obtain the total slag content of iron based on the first vanadium slag content, the second vanadium slag content, and the third vanadium slag content; if the total slag content of iron is >30%, the vanadium slag iron beneficiation process is adjusted to the total slag content of iron ≤30%, and otherwise it is maintained.

[0114] IV. To illustrate the effects of the control method for avoiding vanadium slag loss in iron ore beneficiation provided by this invention, the following example is used for explanation:

[0115] Example 1

[0116] This embodiment provides a method for controlling the loss of vanadium slag in the iron beneficiation of vanadium slag. The specific vanadium slag iron beneficiation process includes: primary crushing - iron beneficiation - secondary crushing - tertiary crushing - quaternary crushing - iron beneficiation - ball milling - iron beneficiation - air classification - iron beneficiation.

[0117] The specific monitoring process is as follows:

[0118] 1) The first and fourth iron removal processes in the crusher mainly involve large pieces of iron, while the fourth process mainly involves tree-like iron.

[0119] ① The five-point sampling method is used to collect samples (including large, medium and small pieces of iron) to obtain the first sample;

[0120] ② Use a hammer to crush the iron block into particles ≤100mm, and separate the slag and iron to obtain the first iron and the first sub-sample;

[0121] ③After the first sub-sample comes out of the crusher, the particle size is ≤38mm. Then, the second iron and the second sub-sample are screened out again.

[0122] ④ The second sub-sample is ground in a grinder to a particle size of ≤0.125mm. The ground material is then screened by a magnet to separate the third iron and the third sub-sample.

[0123] ⑤Then the content of the first vanadium slag = (mass of the third sub-sample / mass of the first sample) × 100%.

[0124] 2) Iron removal at the mill tail: Iron at the mill tail consists of small iron particles that have been screened out by iron balls. The mill iron mainly exists in the form of flattened small iron particles, which serve as the second sample.

[0125] ① After the iron particles pass through the grinding mill, they pass through a 120-mesh sieve to obtain the first sieve sample and the first sieve sample.

[0126] The content of the second vanadium slag is calculated as follows: (mass of the first sieve sample / mass of the second sample) × 100%.

[0127] 3) Iron removal by air classifier: The air classifier uses the working principle of air separation for iron, and the iron selected is iron powder. The air separation of iron by air classifier mainly uses air to separate iron according to the size of the particles. Inevitably, some larger particles of slag will be carried out, which will be the third sample.

[0128] ① Pass the third sample through a 120-mesh sieve to obtain the second sieve upper sample and the second sieve lower sample;

[0129] ② Separate the slag and iron from the second sieve sample to obtain the third sample iron and the third sample slag;

[0130] The content of the third vanadium slag is calculated as follows: (mass of the third sample slag / mass of the third sample) × 100%.

[0131] The total slag content of iron is obtained by multiplying the amount of slag in each section by the proportion of each section's sample in all samples and summing the products. If the total slag content of iron is >30%, the vanadium slag iron beneficiation process is adjusted until the total slag content of iron is ≤30%; otherwise, it is maintained.

[0132] The above process was used for continuous monitoring, and the results are shown in Table 1 below.

[0133] Table 1

[0134]

[0135] In summary, the control method provided by this invention, through a reasonably designed detection process for the vanadium slag content in the product, effectively monitors the vanadium slag content in the product, thereby avoiding excessive loss of vanadium slag during iron selection and ensuring efficient utilization of vanadium in the vanadium slag.
