method of recovering at least one metal from an ore containing at least one metal sulfide, and uses a reagent with a thiocarbonyl functional group and a compound

摘要

This application relates to methods of recovering metals from metal sulfides involving contacting the metal sulfide with an acid sulfate solution containing ferric sulfate and a reagent having a thiocarbonyl functional group, wherein the concentration of reagent in the solution of acid sulphate is sufficient to increase the rate of extraction of metal ions relative to an acid sulphate solution that does not contain the reagent to produce a pregnant solution containing the metal ions.
