Description

Technical Field

[0001] The present invention belongs to the technical field of comprehensive utilization of environmentally friendly building materials and industrial waste residues in nonferrous metallurgy and chemical industry, and relates to a method for comprehensive utilization and recovery of valuable elements of red mud discharged by aluminum industry production enterprises during the production of alumina. Background Art

[0002] Red mud is an industrial solid waste generated during the extraction of alumina by the aluminum industry. It is called red mud because of its high iron oxide content and its resemblance to reddish soil. Depending on the ore grade, production methods, and technological level, approximately 1.0 to 1.8 tons of red mud are emitted for every ton of alumina produced. China, a major alumina producer, emits millions of tons of red mud annually. Red mud is an insoluble residue. Its storage not only occupies a significant amount of land, but its chemical components can also seep into the soil, causing soil alkalinization and groundwater contamination. Long-term exposure to these substances is harmful to human health. The main pollutants in red mud are alkali, fluoride, sodium, and aluminum, at levels exceeding China's national emission standards ("Pollution Control Standards for Solid Waste from the Nonferrous Metals Industry"). The production of large amounts of red mud has had numerous direct and indirect impacts on human production and daily life. Therefore, comprehensive red mud utilization, minimizing its production and hazards, and achieving multi-channel, large-scale resource utilization are urgently needed.

[0003] Most existing alumina plants transport red mud to storage sites, where it is stored wet-processed by building dams. Natural sedimentation allows for separation and partial recycling of the alkali solution. Another method involves drying and dehydrating the red mud before stockpiling. Some companies use dry stockpiling. While this reduces the stockpile volume and allows for increased height, it increases processing costs and still requires land. Furthermore, abundant rainfall in southern China can easily lead to soil alkalization and water pollution. Document (CN202011226543.7) proposes a method and apparatus for the comprehensive utilization of red mud, capable of producing iron ore and titanium ore fines, as well as refractory materials and cement raw materials. While only partial iron and titanium extraction is possible, red mud also contains significant amounts of ferric oxide, aluminum oxide, silicon dioxide, titanium dioxide, magnesium oxide, calcium oxide, and, in particular, rare metals. Document (CN202011226543.7) fails to fully utilize the numerous valuable elements in red mud, leaving its economic value to be further improved. Summary of the Invention

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] See also Figure 1-Figure 5 As shown, the specific embodiments provided by the present invention are as follows:

[0050] Example 1:

[0051] A foam separation method, characterized in that the foam separation method comprises the following steps:

[0052] S1: transfer the material to the trough;

[0053] S2: Transfer the special potion to the trough, and the special potion corresponds to the target concentrate to be separated one by one;

[0054] S3: The force F causes the trough to vibrate;

[0055] S4: The bubbles in the trough float to the liquid surface with the target concentrate to form foam;

[0056] S5: The transfer component transfers the foam with the target concentrate to the concentrate tank;

[0057] S6: Discharge the tailings from the bottom of the trough to the tailings tank.

[0058] The force F is the periodic shaking of the trough.

[0059] Currently, most flotation methods on the market combine stirring and aeration to generate a large number of bubbles, which are then used to float the target concentrate. This is achieved by forcibly introducing air through a fan and then stirring the slurry in the trough to evenly distribute the gas within the slurry. This prevents excessively large bubbles from rapidly rising to the surface, which would otherwise only carry a small amount of the target ore. Furthermore, aeration and stirring must be used in conjunction with each other; otherwise, the bubbles produced are minimal and the flotation effect is limited. Furthermore, stirring and aeration consume significant electrical resources. Existing flotation machines have three to five interconnected reaction tanks, each equipped with a motor driving the agitator. Each motor has a power of 4 to 8 kW. Operating a flotation machine 24 hours a day, the agitator alone consumes 300 to 500 kWh of electricity. For mineral processing companies that operate continuously for extended periods, this flotation method consumes significant energy, making it essential for both resource conservation and cost savings.

[0060] In this embodiment, one embodiment of the foam separation method is as follows Figure 1 As shown, when the special chemical solution and materials enter the trough, it chemically reacts with one or more hydrophilic target minerals in the material, converting them into a target concentrate. The target concentrate is also hydrophobic. In chemistry, hydrophobicity refers to the physical property of a molecule (hydrophobic substance) repelling water. The target concentrate gradually rises to the liquid surface along with the bubbles in the slurry, while other non-target concentrate materials retain their hydrophilicity and sink to the bottom of the trough. Finally, the non-target concentrate materials flow out of the trough through the tailings outlet into the tailings tank.

[0061] The force F causes the trough to vibrate, and the vibrating trough causes the slurry inside to vibrate as well. During the vibration process, a large number of bubbles are generated in the slurry, which float to the liquid surface to form foam, thereby bringing the target concentrate to the liquid surface. The present invention does not require stirring the slurry. The amount of bubbles generated by the present invention not only meets the conditions for separating the target ore, but also saves 300-500 degrees of stirring motor consumption per flotation machine per day, greatly reducing energy waste. Taking the target concentrate as a silicon compound as an example, the special potion only reacts with the silicon compound and produces a hydrophobic silicon compound. Due to its hydrophobic nature, the hydrophobic silicon compound floats to the liquid surface along with the bubbles. Since a foaming agent is added to the slurry, the foam in the slurry is relatively stable and difficult to break. The foam containing the silicon compound is then transferred to the concentrate tank through a transfer component, thereby achieving the effect of separating the silicon compound. It should be noted that the target concentrate can not only be a silicon compound, but also other compounds that can react with the special potion to form lipids, such as aluminum to be separated.

[0062] Example 2:

[0063] A foam separation device, comprising a bracket, a trough, a distribution hopper, a water pipe, a transfer component, a concentrate trough, and a tailings trough, characterized in that it includes:

[0064] The foam separation method;

[0065] Dither component;

[0066] Among them, the shaking component is used to make the trough shake;

[0067] The trough is used to hold the slurry, and the bracket is used to support the trough;

[0068] The open end of the trough is hinged to the bracket, and the bottom of the trough is suspended in the air;

[0069] Wherein, the sub-hopper is used to convey the material to the feeding trough, and the outlet end of the sub-hopper is located above the feeding trough;

[0070] The water pipe is used to transport the special medicine and send the special medicine into the feed tank;

[0071] Wherein, the transfer assembly is used to transfer the foam containing the target concentrate to the concentrate trough, and the transfer assembly is located at the concentrate collection end of the open end of the trough;

[0072] The concentrate trough is used to collect and transport concentrate slurry, and is located below the concentrate collection end of the trough;

[0073] The tailings trough is used to collect and transport tailings slurry, and is located below the tailings outlet.

[0074] Existing flotation machines mainly include mechanical agitation flotation machines and aeration agitation flotation machines. Mechanical agitation flotation machines use a mechanical agitation device consisting of an impeller and a stator to aerate and agitate the slurry. These devices are generally top-gas suction type, where air is drawn in near the mechanical agitation device at the bottom of the flotation cell. The disadvantages of this type of device are low aeration capacity, high power consumption, and significant wear.

[0075] In this embodiment, if Figure 2-3 As shown, a foam separation device is provided, including a bracket, a material trough 1, a distribution hopper 4, a water pipe, a transfer assembly 5, a concentrate trough, and a tailings trough, characterized in that it includes the above-mentioned foam separation method; a shaking assembly; wherein the shaking assembly is used to shake the material trough; wherein the material trough is used to hold slurry, and the bracket is used to support the material trough; wherein the open end of the material trough is hinged to the bracket, and the bottom of the material trough is suspended; wherein the distribution hopper is used to convey the material into the material trough, and the outlet end of the distribution hopper is located above the material trough; wherein the water pipe is used to transmit special medicine and allow the special medicine to be fed into the material trough; wherein the transfer assembly is used to transfer foam with target concentrate to the concentrate trough, and the transfer assembly is located at the concentrate collecting end of the open end of the material trough; wherein the concentrate trough is used to collect and convey concentrate slurry, and the concentrate trough is located below the concentrate collecting end of the material trough; wherein the tailings trough is used to collect and convey tailings slurry, and the tailings trough is located below the tailings mouth.

[0076] If the shaking is irregular, the amount of bubbles generated is uncontrollable, making it difficult to meet mass production requirements. For this reason, the present invention causes the material tank to shake periodically, so that a certain amount of bubbles can be continuously generated in the material tank, effectively improving the separation efficiency.

[0077] Example 3:

[0078] The shaking assembly comprises a connecting shaft, an eccentric wheel and a motor;

[0079] Wherein, the connecting shaft is used to connect the trough and the eccentric wheel, and the two non-overlapping parts on the connecting shaft are part A and part B, and part A is fixedly connected to the outer wall of the trough;

[0080] Wherein, the motor is used to drive the eccentric wheel to rotate.

[0081] In this embodiment, if Figure 2 As shown, the shaking assembly comprises a connecting shaft 31, an eccentric wheel 32, and a motor. The connecting shaft has two non-overlapping parts, namely, part A and part B. Part A is fixedly connected to the outer wall of the trough, and the connecting shaft is used to connect the trough and the eccentric wheel. The motor drives the eccentric wheel to rotate. Driven by the motor, the eccentric wheel causes the connecting shaft to move, thereby causing the trough to periodically move.

[0082] Example 4:

[0083] The eccentric wheel has a vibration-generating component;

[0084] Wherein, the vibration starting component is located at the far point of the periodic motion of the eccentric wheel; and,

[0085] When the eccentric wheel moves to the position of the vibration component, there is a squeezing force between the eccentric wheel and the vibration component, and the vibration component has elastic potential energy;

[0086] The far point position is the position on the outer edge of the eccentric wheel that is farthest from the shaft hole during the periodic motion of the eccentric wheel.

[0087] In this embodiment, if Figure 4 As shown, the eccentric wheel has a vibration assembly; the vibration assembly is located at the farthest point of the eccentric wheel's cyclic motion. When the eccentric wheel moves to the vibration assembly position, there is a squeezing force between the eccentric wheel and the vibration assembly, and the vibration assembly has elastic potential energy. The farthest point is the position on the outer edge of the eccentric wheel that is farthest from the shaft hole during the eccentric wheel's cyclic motion. When the eccentric wheel moves to the vibration assembly position, the eccentric wheel and the vibration assembly are squeezed, and the eccentric wheel is subjected to additional force, causing the eccentric wheel to vibrate, thereby causing the material trough to vibrate and generate more bubbles.

[0088] Example 5:

[0089] The vibration component comprises a damping component and a positioning plate;

[0090] Wherein, the positioning plate is used to carry the damping component,

[0091] When the eccentric wheel moves to the position of the vibration assembly, the damping component is deformed.

[0092] Preferably, the damping member has a second spring 341;

[0093] One end of the second spring 341 is fixed to the positioning plate, and the other end of the second spring 341 faces the eccentric wheel; and,

[0094] When the eccentric wheel moves to the position of the vibration assembly, the end of the second spring 341 facing the eccentric wheel is squeezed, and the second spring 341 is deformed.

[0095] Preferably, the damping member has a screw with a nut;

[0096] The center of the position where the positioning plate is fixedly connected to the second spring 341 has a screw hole for the screw to pass freely. The screw passes through the second spring 341 and the screw hole, and the side of the screw does not contact the second spring 341.

[0097] The nut is located at one end of the screw rod close to the eccentric wheel, and is used to prevent the second spring 341 from extending toward the eccentric wheel.

[0098] The nut and the screw are nested and can be relatively displaced. The nut is located on a side of the positioning plate away from the eccentric wheel.

[0099] In actual factory applications, due to the different contents of the target concentrate to be separated, the requirements for the number and size of bubbles produced are different. Therefore, it is very meaningful to invent a foam grading device that can adjust the bubble size.

[0100] In this embodiment, the damping member 34 has a screw 344 with a nut 343; wherein, the center of the position on the positioning plate 35 that is fixedly connected to the second spring 341 has a screw hole for the screw to pass freely, the screw passes through the second spring 341 and the screw hole and the side of the screw does not contact the second spring 341; wherein, the nut is located at the end of the screw close to the eccentric wheel, and the nut is used to prevent the second spring 341 from extending toward the eccentric wheel; wherein, the nut and the screw are nested and used, the nut 342 and the screw can be relatively displaced, and the nut is located on the side of the positioning plate away from the eccentric wheel. The screw passes through the second spring 341 and the screw hole, and the screw and nut are nested for use. The nut and screw can be displaced relative to the positioning plate. When the eccentric wheel squeezes the nut, because the positioning plate fixes one end of the second spring 341, the nut further squeezes the other end of the second spring 341, causing the second spring 341 to displace. The second spring 341 also exerts a reaction force on the eccentric wheel, thereby exerting an additional force on the eccentric wheel. This additional force causes the eccentric wheel to vibrate, thereby causing the material trough to vibrate and increase the amount of bubbles. In this embodiment, the relative position of the nut and screw can be adjusted to adjust the initial elastic potential energy of the second spring 341.

[0101] Example 7:

[0102] The vibration component has an adjustment track and a locking component;

[0103] The adjusting track is fixed on the bracket, and the positioning plate and the adjusting track are nested for use, so that the positioning plate and the adjusting track can be relatively displaced in the axial direction of the screw;

[0104] Wherein, the locking component is used to lock the relative position of the positioning plate and the adjustment rail.

[0105] The initial elastic potential energy of the vibrating assembly can be adjusted by the relative position of the nut and the screw, but the result of the adjustment may be that the vibrating assembly is too far away from the edge of the eccentric wheel or approaches 0, making the extrusion force between the eccentric wheel and the vibrating assembly too small or 0, thereby losing the force to increase the vibration of the eccentric wheel and failing to achieve the effect of adjusting the bubbles.

[0106] In this embodiment, the positioning plate can be adjusted to reach the distance between the adjusting nut and the eccentric wheel shaft hole, which can ensure that while adjusting the elastic potential energy of the vibrating component, the force of the vibrating component can act on the eccentric wheel to cause it to vibrate, thereby controlling the generation of bubbles.

[0107] Example 8:

[0108] The eccentric wheel has a plurality of non-overlapping vibration components.

[0109] Preferably, the eccentric wheel has a first vibrating component and a second vibrating component;

[0110] Wherein, the first oscillating component is located at a first extreme position, and the second oscillating component is located at a second extreme position;

[0111] Among them, when the connecting shaft undergoes maximum displacement, the two extreme positions corresponding to the connecting shaft are the near-axis position and the far-axis position. When the connecting shaft is at the near-axis position, the position of the point on the eccentric wheel that is the largest distance from the shaft hole is the first extreme position. When the connecting shaft is at the far-axis position, the position of the point on the eccentric wheel that is the largest distance from the shaft hole is the second extreme position.

[0112] Different forces produce different vibration amplitudes, and different vibration amplitudes produce different bubble sizes. Large bubbles are conducive to carrying the target concentrate to float quickly, while small bubbles float slowly and have a greater probability of carrying the target concentrate. Therefore, it is very valuable to adjust the bubble size according to actual needs.

[0113] In this embodiment, the eccentric wheel has multiple non-overlapping oscillating assemblies. Preferably, the eccentric wheel has a first oscillating assembly and a second oscillating assembly; the first oscillating assembly is located at a first extreme position, and the second oscillating assembly is located at a second extreme position. When the connecting shaft experiences maximum displacement, the two extreme positions corresponding to the connecting shaft are the near-axis position and the far-axis position. The first extreme position corresponds to the point on the eccentric wheel at the greatest distance from the axial hole when the connecting shaft is in the near-axis position, while the second extreme position corresponds to the point on the eccentric wheel at the greatest distance from the axial hole when the connecting shaft is in the far-axis position. The spring constant of the second spring 341 can be adjusted by adjusting the relative position of the nut and the screw, and the stroke of the damping element can be adjusted by adjusting the track and locking member. Adjustment can be based on actual needs. For example, when separating a target ore with a low content, increasing the number of small bubbles can improve contact between the bubbles and the target concentrate, while increasing the number of large bubbles can increase the bubble's upward velocity. The spring constant and damping stroke of the first oscillating assembly can be synchronized with the spring constant and damping stroke of the second oscillating assembly. The present invention can increase or decrease the bubble size as a whole to cope with different target mines.

[0114] Example 9:

[0115] The shaking assembly has a first connecting post;

[0116] The first connecting column protrudes from the surface of the eccentric wheel, one end of the first connecting column is fixed at a non-axial hole position of the eccentric wheel, and the other end of the first connecting column is fixedly connected to the B part.

[0117] In this embodiment, the trough is fixedly connected to the connecting shaft 31. The eccentric wheel 32 drives the connecting shaft to generate the force F in S3, causing the trough to displace. Given a certain diameter and rotational frequency, the eccentric wheel can cause the trough to vibrate regularly. This allows the slurry to flow with it. The continuous flow of the slurry not only increases the reaction area between the special solution and the target ore, but also generates bubbles that float on the target concentrate. To obtain the same quality of target concentrate, the special solution required to extract the target concentrate in the present invention is 1 / 2 to 3 / 4 times the amount used in the flotation machine, thereby improving the utilization rate of the special solution and saving the cost of the special solution.

[0118] In one embodiment, the shaking assembly has a support member and a ring;

[0119] The support member is fixed on the bracket, the outer side of the ring is fixedly connected to the support member, and the connecting shaft passes through the ring, and the ring is located between part A and part B;

[0120] The shaking component has a first spring, a second connecting post and a third connecting post;

[0121] The first spring is in non-contact with the eccentric wheel, and the second connecting column protrudes from the surface of the eccentric wheel;

[0122] One end of the second connecting column is fixed to the shaft hole of the eccentric wheel, and the other end of the second connecting column is connected to one end of the first spring;

[0123] One end of the third connecting column is fixed to portion B, and the other end of the third connecting column is connected to the other end of the first spring, and the first spring has a tendency to pull the third connecting column toward the second connecting column.

[0124] In this embodiment, the support member serves as a fulcrum, the connecting shaft serves as a lever, one end of the connecting shaft is fixedly connected to the trough, and the other end of the connecting shaft is tangential to the edge of the eccentric wheel. The second connecting column and the third connecting column are connected by a first spring. The second connecting column is fixed to the shaft hole, and the third connecting column is fixed to portion B of the connecting shaft. The first spring has a tendency to pull the third connecting column toward the second connecting column. When the distance between the tangent point of the connecting shaft and the eccentric wheel and the eccentric wheel shaft hole is the greatest, the trough reaches maximum displacement. When the distance between the tangent point of the connecting shaft and the eccentric wheel and the eccentric wheel shaft hole is the smallest, the trough displacement is zero.

[0125] Taking the target concentrate as silicon compounds as an example, the size of the trough is 2m*4m*4m. For a daily output of 2000t, the foam separation device requires 2-3 troughs, the diameter of the eccentric wheel is 0.9m-1.2m, and the speed of the eccentric wheel is 80 rpm-240 rpm. The purpose is to make the shaking amplitude of the trough not less than 50cm, so as to generate enough bubbles to load the target concentrate.

[0126] Example 10:

[0127] The water pipe has a first liquid pump;

[0128] Wherein, the first liquid pump is used to increase the pressure of the special liquid medicine in the water pipe;

[0129] The water pipe comprises an inner water pipe, an outer water pipe and a connecting end;

[0130] Wherein, the outer water pipe is located outside the trough and can be deformed;

[0131] Wherein, the inner water pipe is located inside the trough and cannot be deformed;

[0132] Wherein, the connecting end is sealedly connected to the bottom of the trough;

[0133] The inner water pipe has at least one branch water pipe, and the branch water pipe has at least one water outlet, which is vertically upward.

[0134] In this embodiment, since the outer water pipe 21 is located outside the trough and the trough will undergo relative displacement, the outer water pipe will also be displaced accordingly. The outer water pipe is very easy to be damaged during the continuous shaking of the trough. Therefore, the outer water pipe needs to have a certain degree of elasticity and deformation, which is more conducive to extending the service life of the outer water pipe. Among them, the connecting end 22 is sealed with the bottom of the trough, the inner water pipe 23 has no less than one branch water pipe, and the branch water pipe 231 has no less than one water outlet 232, and the water outlet is vertically upward. In the same time period, setting multiple locations and multiple water outlets can increase the contact area between the special medicine and the material, thereby accelerating the reaction time and increasing the daily output of foam separation. Setting a first liquid pump in the water pipe can increase the speed at which the special medicine enters the slurry, so that the special medicine can be sprayed upward.

[0135] In one embodiment, a gas pipe is provided; the gas pipe is used to input gas into the slurry.

[0136] The air outlet of the air pipe is located in the lower middle part of the trough;

[0137] The distance between the middle and lower part and the bottom of the trough is 1 / 5 to 1 / 3 of the height of the trough.

[0138] The air outlet of the air pipe is toward the bottom of the trough.

[0139] In this embodiment, gas is introduced into the slurry through an air pipe, thereby increasing the amount of bubbles in the slurry and increasing the amount of bubbles within the same time period. In this case, the air outlet of the air pipe is located at a distance from the bottom of the trough that is 1 / 5 to 1 / 3 of the trough height, and the air outlet of the air pipe is directed toward the bottom of the trough. The gas from the air pipe is ejected toward the bottom of the trough, and the bubbles at the bottom can bring the target concentrate at the bottom of the trough to the liquid surface. The air outlet of the air pipe directed toward the bottom of the trough prevents the air outlet from being blocked by material, thereby increasing the service life of the air outlet.

[0140] In one embodiment, the distribution hopper comprises a main body and a distribution pipe extending from the main body, the distribution hopper comprises a plurality of distribution pipes, the outlet end of the distribution pipe comprises a feeding member, the feeding member is in the shape of a shower head, and the discharge port of the feeding member faces the trough;

[0141] The feeding component has multiple discharge ports, which are evenly distributed on the bottom surface of the feeding component, and the distance between two adjacent discharge ports is 3cm-10cm;

[0142] The sub-hopper is used to feed materials into different troughs respectively, and the connecting shaft is fixedly connected to the side walls of different troughs.

[0143] In this embodiment, the distribution hopper has a main body and a distribution pipe 41 extending from the main body. The distribution hopper has multiple distribution pipes. The outlet end of the distribution pipe has a feeding component 411. The feeding component is in the shape of a shower head, and the discharge port 412 of the feeding component faces the material trough; the feeding component has multiple discharge ports, which are evenly distributed on the bottom surface of the feeding component, and the distance between two adjacent discharge ports is 3cm-10cm; the distribution hopper is used to feed materials into different material troughs respectively, and the connecting shaft is fixedly connected to the side walls of different material troughs. The distribution hopper 4 delivers the material to multiple troughs simultaneously through the distribution pipe. The connecting shaft is fixedly connected to the side walls of different troughs. An eccentric wheel can simultaneously drive multiple troughs to move. Taking 5 troughs as an example, compared with a flotation machine with 5 reaction tanks, the power consumption for 24 hours is 400-500 degrees. The present invention drives the 5 troughs to move through a motor. The 24-hour power consumption of the motor driving the eccentric wheel is 100-120 degrees. The power consumption of the present invention is 1 / 4 of the power consumption of the flotation machine, which greatly saves the cost of mineral processing. In addition, the feed component has multiple discharge ports, which are evenly distributed on the bottom surface of the feed component. The distance between two adjacent discharge ports is 3cm-10cm, which increases the contact area between the material and the special potion and increases the reaction area between the target ore and the special potion.
