| titleOfInvention | A kind of separation method of indium, copper, arsenic and zinc in polymetallic sulfuric acid solution |
| abstract | The invention relates to a method for separating indium, copper, arsenic and zinc in a polymetallic sulfuric acid solution, and belongs to the technical field of metallurgical environmental protection. The invention adopts organic solvent to extract indium from sulfuric acid solution containing copper, zinc, indium and arsenic to obtain indium-extracted residual liquid and indium-loaded organic phase; the obtained indium-extracted residual liquid is decoppered to obtain decoppered liquid and an indium-loaded organic phase. copper-containing sulfide minerals; arsenic precipitation in the obtained decopper solution to obtain iron arsenate crystals and arsenic precipitation post solution; zinc extraction with organic solvent from the obtained arsenic precipitation post solution to obtain zinc extraction residual solution and zinc-loaded organic phase. The method of the invention has the advantages of less environmental pollution, good metal separation and recovery effect, good economic benefit and the like. |
