Use of reagents with thiocarbonyl functional groups and methods of recovering base metals from base metal sulfides

摘要

PROBLEM TO BE SOLVED: To provide a method for recovering a metal from a metal sulfide. SOLUTION: The step of contacting a metal sulfide with an acidic sulfate solution containing a ferric sulfide and a reagent having a thiocarbonyl functional group is included, and the concentration of the reagent in the acidic sulfate solution includes the reagent. It is sufficient to increase the extraction rate of metal ions compared to a non-acidic sulfate solution and produces a noble solution containing metal ions. [Selection diagram] None
