Biological Leaching-Pressure Oxidation for Auriferous ...

A process has been evaluated, on a continuous pilot plant scale, to treat refractory gold arsenopyrite/pyrite . concentrates. The process consisted of biological leaching to partially oxidise sulphides, followed by pressure leaching for complete sulphide oxidation and arsenic precipitation, followed by liquor neutralisation and cyanidation of the autoclave residue for gold recovery.
