    Both sulfide and oxide copper minerals can be consumers of cyanide. In the case of native copper or oxide copper minerals sulfuric acid leaching can remove the copper prior to cyanidation. Sulfide minerals that consume cyanide are typically preconcentrated by flotation before being oxidized using roasting pressure oxidation or bio-oxidation.
