Process flowsheet for gold and antimony recovery from

Process Flowsheet For Gold And Antimony Recovery From

Abstract Recovery of gold from refractory ores requires a pretreatment to liberate the gold particles from the host mineral. In particular, in the case of stibnite (Sb 2 S 3 ), the antimony (Sb) forms stable compounds with sodium cyanide (NaCN) during the cyanidation process as a consequence, cyanide consumption increases. Pretreatment is usually an oxidation step.
