[0008] An energy-saving and environmentally friendly mineral processing equipment that replaces a shaking table, comprising a vibrating feeder 1, a slurry barrel 2 is arranged below the discharge port of the vibrating feeder 1, a stirrer 5 is arranged in the slurry barrel 2, a first slurry outlet 6 is arranged at the bottom of the slurry barrel 2, the stirrer 5 is connected to a first DC motor 4, the first slurry outlet 6 is connected to a funnel 9 through a mud pump 7, the discharge port of the funnel 9 is arranged at a ore separation cone bucket 13 and is arranged directly opposite to a fixed disc 10, and the fixed disc 10 is arranged on a support rod through an adjusting screw 11 On the top, the support rod is overlapped and fixed on the barrel edge of the outer barrel 18, an inner barrel 19 is arranged in the outer barrel 18, a concentrate trough 16 is arranged between the outer barrel 18 and the inner barrel 19, a diverter plate 14 is arranged on the outer wall of the ore separation conical bucket 13, the diverter plate 14 is connected and matched with the concentrate trough 16, and a concentrate outlet 17 of the concentrate trough 16 is arranged outside the outer barrel 19, and the bottom of the ore separation conical bucket 13 is a second slurry outlet 15, and its discharge pipe is fixed by a bearing 12 and a pulley 21 is arranged on it to connect the second DC motor 20.

[0009] The diverter plate 14 is annularly arranged on the outer wall of the ore separation cone bucket 13 .

[0010] The concentrate tank 16 is disposed between the outer barrel 19 and the inner barrel 18 and is sealed with the outer barrel 19 and the inner barrel 18 .

[0011] A slurry receiving plate 22 is provided at the second slurry outlet 15, and the two are connected and matched.

[0012] A water jacket 3 is arranged on the periphery of the slurry barrel 2 .

[0013] Working principle of the present invention: The vibrating feeder adds the tailings into the slurry barrel through the first DC motor and the agitator. The water and ore are mixed into slurry in a certain proportion. The water jacket is heated to 75 degrees Celsius for constant temperature. After being mixed evenly, it is sent to the mud pump through the first slurry outlet and sent to the funnel through the pipeline. Then the slurry falls into the fixed disc. The fixed disc can be adjusted to rise and fall by adjusting the screws. The separation cone bucket is fixed by the bearing. The mud and tailings flow out from the second slurry outlet. The concentrate flows into the concentrate trough after being diverted by the diverter plate, and then flows out from the concentrate outlet. The outer barrel is used for protection, and the inner barrel plays the role of fixing the concentrate trough. The second DC motor can be infinitely speed-regulated to control the speed of the separation cone bucket. The mud and tailings receiving plate is used to receive the mud and tailings flowing out of the second slurry outlet, which can be discharged externally.

[0014] Example 1 Use 200L of tap water and 50kg of tailings to add into the slurry barrel and stir evenly. Start the mud pump to work. The tailings and mud are discharged from the second slurry outlet, and the concentrate flows out from the concentrate outlet. All the work is completed.

[0015] In terms of yield: the original tailings contain 0.3% tin, and the concentrate contains 1.5% tin after selection by the first unit. The tin content after selection by the second unit is 3.0%, and the third unit... and so on.

[0016] Energy consumption: Each unit can control about 0.8 kWh of DC electricity per hour.

[0017] Example 1 The raw ore is crushed to 325 mesh for use, 50L of tap water, 25KG of sodium hydroxide, and 20KG of mineral powder are added to make slurry, which is added to the electrolytic barrel with a stirrer. The electrolysis is circulated in the electrolytic barrel through the mud pump. The sponge lead and sponge zinc deposited at the negative electrode are smelted into lead ingots and zinc ingots. Gold and silver are recovered from the anode mud. After electrolysis, the electrolyte is filtered by a plate and frame machine, and the sodium hydroxide is returned for preparation. The filter residue is washed to neutrality to complete the building materials and cast stone.

[0018] This process does not use any acid and has no impact on the environment. It uses alkali for leaching and electrolysis to achieve energy conservation and environmental protection. The drugs can be reused to achieve zero emissions, which meets national requirements.
