Process flow-sheet for gold and antimony recovery from stibnite

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 …
