Abstract: This application pertains to methods of recovering metals from metal sulfides that involve contacting the metal sulfide with an acidic sulfate solution containing ferric sulfate and a reagent that has a thiocarbonyl functional group, wherein the concentration of reagent in the acidic sulfate solution is sufficient to increase the rate of metal ion extraction relative to an acidic sulfate solution that does not contain the reagent, to produce a pregnant solution containing the metal ions.

Abstract: The present disclosure relates to the use of a wetting agent such as a non-ionic wetting agent and a reagent comprising a thiocarbonyl functional group, for example, in a method/process or use for extracting a base metal such as copper from a material comprising the base metal. Such methods/processes can comprise contacting the material under acidic conditions with the wetting agent and the reagent comprising the thiocarbonyl functional group; and optionally recovering the base metal.

Abstract: The present disclosure relates to a method using a reagent having a thiocarbonyl functional group to liberate a precious metal such as gold from a material comprising a sulfide, wherein the sulfide encapsulates the precious metal. Such a method comprises contacting the material under acidic conditions with the reagent comprising the thiocarbonyl functional group and optionally producing a residue comprising the precious metal. The present disclosure also relates to the use of a reagent having a thiocarbonyl functional group in methods for extracting a precious metal from a material comprising a sulfide, wherein the sulfide encapsulates the precious metal, the method comprising leaching the precious metal from a residue comprising the precious metal produced from such a method for liberating a precious metal.
