ABSTRACT

Hydrometallurgical methods for preparation of refractory arsenopyrite concentrates to cyanidation using bacterial leaching and chemical decomposition have been investigated. After cyanide or non-cyanide gold dissolution, the complexes of gold can be selectively recovered on acrylic or styrene anion exchangers.
