[0027] According to the above content, during the separation process, after the staff adds the sulfide slag and the sulfuric acid solution into the interior of the slag leaching round tank 301, the exhaust bracket 302 will rotate at a constant rate under the action of the driving component 304. When the exhaust bracket 302 rotates, the sulfide slag and the sulfuric acid solution will be fully mixed to form a slurry.

[0028] At the same time, the oxygen storage tank 305 will fill the exhaust cavity with oxygen through the rotary joint. Figure 5 As shown, oxygen will be discharged upward through a plurality of exhaust square holes 303, and then the oxygen will chemically react with the slurry, thereby converting the target non-ferrous metal element and sulfide form into ion form.

[0029] In this embodiment, by setting up an oxidation leaching mechanism 3 and utilizing the mutual cooperation between the exhaust support 302 and the drive assembly 304, the sulfide slag raw material to be extracted and the sulfuric acid solution can be fully mixed under normal pressure, thereby pre-activating the sulfide slag, which can improve the leaching rate of the target non-ferrous metals in the oxidation leaching process to a certain extent; moreover, in this embodiment, by setting up an oxidation leaching mechanism 3 and utilizing the mutual cooperation between the oxygen storage tank 305 and the exhaust support 302, oxygen can flow upward in a spiral from the bottom of the leaching slag round tank 301, which can effectively increase the contact area between oxygen and the slurry, so that oxygen and the slurry can fully react, which can also improve the leaching rate of the target non-ferrous metals.

[0030] Embodiment 2 In order to increase the contact area between the sulfide slag and the sulfuric acid solution and improve the efficiency of the sulfide slag preactivation, based on Example 1, Figure 1 , Figure 2 ,as well as Figure 6-Figure 8 As shown, the present embodiment is provided with a slag processing mechanism 4. Specifically, the slag processing mechanism 4 comprises a rectangular cover plate 401 fixedly mounted on the upper end of the slag leaching round tank 301. A mounting bracket 402 is fixedly mounted on the upper end of the rectangular cover plate 401. A fixed screw rod 403 is arranged on the mounting bracket 402. A grinding gear 404 is movably mounted on the fixed screw rod 403. The grinding gear 404 is threadedly matched with the fixed screw rod 403. When the grinding gear 404 rotates under the action of a driving gear 4052, it moves up and down along the fixed screw rod 403. A power assembly 405 for driving the grinding gear 404 is arranged on the side of the mounting bracket 402. The power assembly 405 comprises a fixed platform 405 arranged on the mounting bracket 402. 51. A driving gear 4052 is movably mounted on the lower end of the fixed platform 4051, and a driving motor 4053 is fixedly mounted on the upper end of the fixed platform 4051. The outer surface shape of the driving gear 4052 matches the outer surface shape of the grinding gear 404. When the driving gear 4052 rotates, the grinding gear 404 will rotate synchronously. A plurality of grinding protrusions 406 are arranged on the lower end of the grinding gear 404. A rotating baffle 407 is movably mounted on the rectangular cover plate 401, and a shielding circular cover 408 is fixedly mounted on the upper end of the rectangular cover plate 401. Initially, the rotating baffle 407 is in a horizontal state. When the rotating baffle 407 rotates downward, the ground sulfide slag will fall into the interior of the slag leaching round tank 301.

[0031] According to the above content, when separating the sulfide slag, the staff will put the sulfide slag fragments obtained after the crushing process into the inside of the shielding circle 408. Next, the grinding gear 404 will rotate under the action of the driving gear 4052. When the grinding gear 404 rotates, it will grind the sulfide slag fragments through cooperation with the grinding protrusion 406.

[0032] Moreover, during the rotation of the grinding gear 404, it will move reciprocatingly downward under the action of the fixed screw 403, so that the sulfide slag is automatically squeezed while grinding, which can effectively improve the efficiency and effect of grinding.

[0033] After grinding for a certain period of time, the rotating baffle 407 will automatically rotate downward to a vertical state, so that the powdered sulfide slag falls into the interior of the slag leaching round tank 301, realizing automatic feeding without the need for manual feeding by staff.

[0034] In this embodiment, by providing a slag processing mechanism 4 and utilizing the mutual cooperation between the grinding gear 404 and the grinding protrusion 406, the sulfide slag fragments can be automatically ground during feeding, so that the blocky sulfide slag is turned into powder, which can effectively increase the contact area between the sulfide slag and the sulfuric acid solution, thereby improving the efficiency and effect of the sulfide slag pre-activation; moreover, in this embodiment, by providing a slag processing mechanism 4 and utilizing the mutual cooperation between the fixed screw rod 403 and the power assembly 405, the grinding gear 404 can be moved downward during grinding, thereby squeezing and crushing the sulfide slag fragments, which can effectively improve the efficiency of the grinding process and also prevent the debris from splashing around to a certain extent.

[0035] Embodiment 3 In order to help the staff to more accurately grasp the amount of sulfuric acid solution added, based on the above embodiment, Figure 1 , Figure 2 , Fig. 9 as well as Fig.10 As shown, the quantitative liquid injection mechanism 5 is provided in this embodiment. Specifically, the quantitative liquid injection mechanism 5 includes a mounting plate 501 fixedly mounted on the side of the rectangular cover plate 401, a circular pipe 502 is fixedly mounted on the mounting plate 501, the upper end of the circular pipe 502 is connected with a liquid inlet pipe 503, a one-way valve is arranged inside the liquid inlet pipe 503 to allow liquid to flow into the circular pipe 502 in one direction, a liquid discharge elbow 504 is connected to one side of the circular pipe 502, the liquid discharge elbow 504 extends to the inside of the residue immersion round tank 301, and a detachable mounting plate 506 is arranged on the liquid discharge elbow 504. There is a fan-shaped nozzle 505, and a plurality of liquid spraying circular holes 508 are opened on the fan-shaped nozzle 505. When the sulfuric acid solution is sprayed outward through the liquid discharge elbow 504, it will be sprayed outward through the plurality of liquid spraying circular holes 508 at the same time, so that the sulfuric acid solution flows downward along the inner wall of the slag leaching round tank 301. A telescopic push rod 506 is arranged on the other side of the circular pipe 502. A liquid pushing piston 507 is slidably connected inside the circular pipe 502. When the liquid pushing piston 507 moves horizontally, the sulfuric acid solution inside the liquid inlet circular pipe 503 will be sprayed outward through the liquid discharge elbow 504.

[0036] According to the above content, it can be known that when the slag falls downward, the rotating baffle 407 will be in a vertical state. At the same time, the sulfuric acid solution will enter the interior of the circular pipe 502 through the liquid inlet pipe 503. Next, the liquid pushing piston 507 will move horizontally under the action of the telescopic push rod 506. When the liquid pushing piston 507 moves, the sulfuric acid solution inside the circular pipe 502 will enter the interior of the liquid discharge elbow 504.

[0037] Then, if Fig. 9 As shown, the sulfuric acid solution will be sprayed outward through the multiple liquid spray holes 508 on the fan-shaped nozzle 505, so as to flush the inner wall of the rotating baffle 407 and the slag leaching round tank 301, and wash off the sulfide slag powder adhering to the rotating baffle 407 and the slag leaching round tank 301, which can effectively avoid waste.

[0038] After one liquid addition is completed, the liquid pushing piston 507 will be reset under the action of the telescopic push rod 506. Next, the one-way valve inside the liquid inlet tube 503 will automatically open, and the sulfuric acid solution will enter the interior of the circular pipe 502 through the liquid inlet tube 503, and so on, thereby adding the sulfuric acid solution to the interior of the leaching tank 301 in multiple times.

[0039] In this embodiment, by setting a quantitative liquid injection mechanism 5, the circular pipe 502 and the fan-shaped nozzle 505 cooperate with each other, so that the sulfuric acid solution can be sprayed horizontally at the upper end of the inner cavity of the slag leaching round tank 301, which can not only rinse the rotating baffle 407, but also wash off the sulfide slag powder adhering to the inner wall of the slag leaching round tank 301, which can effectively avoid waste; moreover, in this embodiment, by setting a quantitative liquid injection mechanism 5, the circular pipe 502 and the telescopic push rod 506 cooperate with each other, so that the sulfuric acid solution is added to the interior of the slag leaching round tank 301 in multiple times, which can not only repeatedly rinse the rotating baffle 407 and the slag leaching round tank 301, but also help the staff to more accurately grasp the addition amount of the sulfuric acid solution, which is convenient to use.

[0040] Embodiment 4 In order to improve the integration of the device and help the staff to quickly obtain the filter residue, based on the above embodiment, Figure 1 and Figure 2 As shown, the present embodiment is provided with an auxiliary unloading mechanism 6.

The annular bracket 603 is fixedly sleeved on the outside of the leaching slag round tank 301. A driving motor 604 for driving the annular bracket 603 is provided on the fixed bracket 2. When the annular bracket 603 rotates, the leaching slag round tank 301 will be rotated synchronously, thereby helping the staff to quickly pour out the slurry.

[0041] According to the above content, after a certain period of oxidative leaching, the annular bracket 603 will rotate under the action of the driving motor 604. When the annular bracket 603 rotates, the leaching residue round tank 301 will rotate synchronously. At the same time, the baffle plate will automatically release the blockage of the discharge port.

[0042] Next, the slurry in the slag leaching round tank 301 will drop into the inside of the receiving box 601 through the discharge port, and then the filter screen plate 602 will filter the slurry to obtain filter residue and filtrate.

[0043] Next, the staff will carry out pressurized oxidation leaching on the filter residue, and then remove impurities from the obtained leachate to obtain a sulfate solution containing the target metal.

[0044] This embodiment provides an auxiliary unloading mechanism 6 and utilizes the cooperation between the receiving box 601 and the filter screen plate 602 to automatically filter the slurry after the normal pressure oxidation leaching process, thereby helping the staff to quickly obtain the filter residue. It has a high degree of integration and does not require the staff to transfer and manually handle the slurry, making it easy to use.

The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field.
