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.

Abstract: The present disclosure relates to the use of carbonaceous matter and a reagent comprising a thiocarbonyl functional group, for example, in a method for extracting a base metal such as copper from a material comprising the base metal. Such methods can comprise contacting the material under acidic conditions with the carbonaceous matter and the reagent comprising the thiocarbonyl functional group; and optionally recovering the base metal.
