Technology for comprehensively recovering complex material containing lead, bismuth, cobalt and nickel through wet method

The present invention relates to a process for recovering lead, bismuth integrated wet cobalt-nickel complex lead-containing materials of this bismuth cobalt and nickel materials, ball-milling the first milled to 200 mesh, and mixed acid leaching bismuth, cobalt, nickel and lead remaining in the slag, leachate Shen first hydrolyzed and bismuth, and then on cobalt oxide, and finally adding soda Nickel, achieve the effect of wet processing integrated recovery of cobalt and nickel separation of lead-bismuth. The process is simple, adaptability of raw materials, low cost, can be more rational use of the material separating valuable metal resources.
