Description

Technical Field

[0001] The present application relates to the technical field of physical mineral separation, and in particular to a physical mineral separation device capable of performing water circulation treatment. Background Art

[0002] Currently, phosphate rock processing technologies primarily include physical beneficiation, chemical beneficiation, and biological beneficiation. Physical beneficiation is widely used due to its simplicity and low cost. Physical beneficiation primarily involves crushing, screening, grinding, grading, gravity separation, magnetic separation, and flotation, effectively separating and purifying phosphate rock.

[0003] The water circulation system is a crucial component of the physical mineral processing process. It recycles the water generated during the mineral processing process, reducing water waste and minimizing environmental impact. Traditional physical mineral processing equipment with a water circulation system typically includes equipment such as a clear water tank and a return water tank, which enable water recycling.

[0004] However, with the continuous expansion of phosphate rock processing and increasing processing requirements, traditional physical mineral processing equipment with water circulation systems has gradually exposed some problems. Among them, the most prominent issue is the inadequate treatment and utilization of wastewater. During the physical mineral processing process, wastewater such as overflow water from the thickener and filtrate from the filter press is often difficult to effectively treat and fully utilize in traditional water circulation systems. If this wastewater is directly discharged, it not only wastes water resources but also may pollute the surrounding environment. Therefore, how to better utilize and treat this wastewater has become a technical problem that needs to be solved in current physical mineral processing equipment with water circulation systems.

[0025] The following will clearly and completely describe the concept, specific structure and technical effects of this application in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features created in this application can be combined interactively without conflicting with each other.

[0026] like Figure 1 As shown, a physical mineral processing device capable of water circulation treatment includes a high-level water tank 11, wherein the high-level water tank 11 is used to introduce the clean water in the high-level water tank 11 into the ball mill 21, the first thickener 22 and the return water tank 12;

[0027] The return water tank 12 is used to receive the clean water from the high-level water tank 11 and the overflow water from the first thickener 22 , and is used to guide the return water in the return water tank 12 into the ball mill 21 and the flotation machine 23 .

[0028] Specifically, the high-level water tank contains clean water from outside. Clean water includes tap water, deionized water, and distilled water. External water refers to water from treatment stations, water stations, and other equipment that provides clean water.

[0029] More specifically, the high-level water tank is equipped with an inlet pipe and an outlet pipe. The inlet pipe is used to receive clean water from the outside; the outlet pipe is connected to the ball mill, the first thickener, and the return water tank, and delivers clean water to these devices through pumping.

[0030] Specifically, the return water tank is responsible for receiving clean water from the high-level water tank or return water from other equipment.

[0031] In some embodiments, the ball mill 21 is connected to a flotation machine 23 , the flotation machine 23 is connected to a first thickener 22 , and the first thickener 22 is connected to a first filter 24 .

[0032] Specifically, during the material beneficiation process, a ball mill receives raw ore, which is then milled with water to obtain ball-milled ore with a required particle size. The ball-milled ore with the required particle size is introduced into a flotation machine where water is added for flotation. The flotation ore obtained after flotation is introduced into a first thickener for thickening to obtain thickened ore and first overflow water. The thickened ore is then processed through a first filter to obtain a first filtrate and concentrate.

[0033] In some embodiments, the liquid inlet of the ball mill 21 is connected to the high-level water tank 11 and the return water tank 12 respectively.

[0034] During specific operations, the clean water from the high-level water tank or the return water from the return water tank can be introduced into the ball mill and mixed with the original ore for ball milling, so as to make full use of the return water generated by the mineral processing equipment.

[0035] In some embodiments, the liquid inlet of the flotation machine 23 is connected to the return water tank 12 .

[0036] Specifically, the return water in the return water tank can be introduced into the flotation machine for flotation treatment, thereby making full use of the return water generated by the mineral processing device.

[0037] In some embodiments, the liquid inlet pipe of the first thickener 22 is connected to the high-level water tank 11 , and the overflow pipe of the first thickener 22 is connected to the return water tank 12 .

[0038] Specifically, the first thickener receives clean water from the high-level water tank through the liquid inlet pipe and performs thickening treatment; during the thickening treatment process, the first overflow water generated by the first thickener is introduced into the return water tank and used as return water.

[0039] In some embodiments, the liquid outlet pipe of the first filter 24 is connected to the return water tank 12 .

[0040] Specifically, the first filter performs filtration processing to produce concentrate and a first filtrate, and the first filtrate is introduced into the return water tank and used as return water.

[0041] In some embodiments, the flotation machine 23 is further connected to a second thickener 25 , and an overflow pipe of the second thickener 25 is connected to the return water tank 12 .

[0042] Specifically, during the flotation process of the flotation machine, tailings are generated; the tailings are introduced into the second thickener for thickening treatment, and the second overflow water generated is introduced into the return water tank and used as return water.

[0043] In some embodiments, the second thickener 25 is connected to a second filter 26 , and an outlet pipe of the second filter 26 is connected to the return tank 12 .

[0044] Specifically, the second filter performs filtration processing to produce tailings and a second filtrate, and the second filtrate is introduced into the return water tank and used as return water.

[0045] In some embodiments, the discharge pipe of the first filter 24 is connected to the storage yard 27 .

[0046] Specifically, the concentrate produced by the filtration process of the first filter is introduced into the stockpile to be processed in the next step.

[0047] In some embodiments, the discharge pipe of the second filter 26 is connected to a filling station 28 .

[0048] Specifically, the tailings generated by the filtration process of the second filter are introduced into the filling station to be filled.

[0049] Specifically, such as Figure 1 As shown, in the physical mineral processing device capable of water circulation treatment in this application, the high-level water tank is used to store clean water, providing water for the ball mill, the first thickener, and the return water tank, ensuring a stable supply of clean water during the mineral processing process and reducing the consumption of new water. The high-level water tank can be a water storage tank.

[0050] The return water pool collects and stores wastewater generated during the mineral processing process and reuses it in the mineral processing process, thereby realizing the recycling of wastewater, reducing wastewater discharge and lowering environmental pollution.

[0051] Specifically, the models and sizes of the ball mill, the first thickener, the flotation machine, and the second thickener can be selected according to actual production needs; the first filter can be a ceramic filter, and the second filter can be a filter press.

[0052] Specifically, water recycling in a physical beneficiation unit primarily involves the elevated water tank, the return water tank, and the corresponding piping connecting the elevated water tank to other equipment in the physical beneficiation unit, as well as the corresponding piping connecting the return water tank to other equipment in the physical beneficiation unit. The return water tank, therefore, serves as the central wastewater collection and storage center, receiving clean water from the elevated water tank as well as various wastewaters generated during the beneficiation process (such as overflow water from the first thickener and filtrate from the first filter). Through centralized treatment in the return water tank, this wastewater can be reused in the ball mill and flotation machine, thus achieving wastewater recycling.

[0053] like Figure 2 As shown in this application, the operation process of the physical mineral processing device capable of water circulation treatment is as follows:

[0054] The clean water in the high-level water tank is introduced into the ball mill to be mixed with the raw ore and ball-milled.

[0055] The milled pulp is introduced into the flotation machine for flotation treatment to separate useful minerals and tailings.

[0056] The useful minerals after flotation are introduced into the first thickener for thickening treatment, producing concentrated mineral material and first overflow water. The first overflow water is introduced into the return water tank.

[0057] After the concentrated ore is filtered through the first filter, the concentrate and the first filtrate are obtained. The first filtrate is also introduced into the return water tank.

[0058] The tailings produced during the flotation process are introduced into the second thickener for thickening, producing second overflow water and tailings. The second overflow water is also introduced into the return water tank.

[0059] The tailings slurry is filtered through the second filter to obtain tailings and a second filtrate, which is also introduced into the return water tank.

[0060] The return water in the return water pool is reintroduced into the ball mill and flotation machine for recycling.

[0061] The above is a specific description of the preferred implementation of the present application, but the invention of the present application is not limited to the described embodiments. Technical personnel familiar with the art can also make various equivalent modifications or substitutions without violating the spirit of the present application. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
