Description
Technical Field
The utility model relates to a solid-liquid separation device, in particular to a copper-cobalt wet smelting leaching residue solid-liquid separation device.
Background
Copper-cobalt wet smelting is to leach ore with sulfuric acid, react copper-cobalt and other valuable metals with sulfuric acid, enter solution in ionic form, separate solid from liquid, obtain valuable metal-containing solution, perform subsequent extraction, electrodeposition and other treatments to obtain product electrolytic copper, or use raffinate to neutralize iron, precipitate magnesium oxide and other materials to produce coarse hydrogen-producing cobalt oxide, while the residual leached slag (tailings) is discharged as waste material. At present, solid-liquid separation is mainly realized by dense separation-CCD washing (countercurrent washing of a four-to-five-stage thickener). Counter-current washing of the thickener, namely, the pulp and the washing water move in opposite directions, copper ion exchange is carried out by utilizing the difference of copper content in pulp and washing water of the multi-stage thickener through concentration difference, copper ions are concentrated step by step into top flow clear liquid of the thickener, and tailing pulp (leaching residue) is discharged at bottom flow of the thickener of the last stage. The solid-liquid separation technology is continuous operation and low in operation cost, but valuable metal solution and tailings are difficult to fully separate, so that the solid concentration of the tailings slurry reaches 55%, and the tailings slurry contains a large amount of valuable metals such as copper and cobalt, sulfuric acid and the like, so that the raw materials are lost, and alkali is added to neutralize the tailings slurry before final discharge so as to reach the discharge standard, and the production cost is increased. Meanwhile, as the tailing slurry cannot be discharged dry, the subsequent risks of environmental pollution, dam break and the like exist.
Disclosure of Invention
The utility model aims to solve the technical problems in the prior art and provides a copper-cobalt wet smelting leaching residue solid-liquid separation device.
The technical scheme of the utility model is as follows: the solid-liquid separation device for the copper-cobalt wet smelting leaching slag is provided with a cyclone, a horizontal decanter centrifuge, a dewatering screen, a plate-and-frame filter press, a solution storage tank and a dry tailing discharging reservoir, wherein the cyclone is used for carrying out particle size classification on the copper-cobalt wet smelting leaching slag, overflow materials of the cyclone enter the horizontal decanter centrifuge, and underflow materials of the cyclone enter the dewatering screen; the horizontal decanter centrifuge is used for carrying out solid-liquid separation on overflow materials, the obtained first solid materials enter a dry tailing discharging warehouse, and the obtained first liquid materials enter a plate-and-frame filter press; the dewatering screen is used for carrying out solid-liquid separation on the underflow material, the obtained second solid material enters a dry tailing discharging warehouse, and the obtained second liquid material enters a plate-and-frame filter press; the plate-and-frame filter press is used for carrying out solid-liquid separation on the first liquid material and the second liquid material, the obtained third solid material enters a dry tailing discharging warehouse, and the obtained third liquid material enters a solution storage tank.
The utility model further processes the copper-cobalt wet smelting leaching slag, the cyclone can divide the leaching slag into coarse materials with large particles and fine materials with small particles, then the coarse materials are effectively removed through the dewatering screen, the fine materials are further separated through the horizontal screw centrifuge, and the liquid materials obtained by the separation of the dewatering screen and the horizontal screw centrifuge are combined and are subjected to solid-liquid separation again through the plate-and-frame filter press. The solid materials obtained by the dewatering screen, the horizontal decanter centrifuge and the plate-and-frame filter press are dry tailings with the water content less than 15 percent; a large amount of valuable metals such as copper and cobalt contained in the leaching residue and sulfuric acid remain in the liquid obtained by the plate-and-frame filter press. Compared with the prior art, on one hand, the utility model saves the material investment without alkali neutralization, and avoids the subsequent risks of environmental pollution, dam break and the like caused by the inability of dry discharge of tailing slurry; on the other hand, the activity of sulfuric acid in the solution is released through solid-liquid separation, so that the liquid material can be returned to the original system to be used as the supplement of new acid, and can also be combined with new water in the original process to be returned to the washing system again, valuable metals and residual acid in the solution are effectively extracted until the extraction section, the overall recovery rate of the metal is improved by 1-2%, and the acid consumption is reduced by 10-20%. Meanwhile, the method has the advantages of continuous operation, simple operation and the like, and greatly reduces the cost of copper-cobalt wet smelting.
