Process flow-sheet for gold and antimony recovery

2000-10-1  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.

The Treatment of Antimonial Gold Ores

The only simple sulphide mineral of antimony of importance is stibnite, SbS3, containing 718% antimony when pure. It is lead-grey, has a densityof 45 to 46 and melts at 546C. It is both friable and sectile (Hardness 2 on Moh's scale) and, as a result, slimes very readily during milling.It is commonly associated with pyrite and arsenopyrite other minerals occurring with stibnite in minor ...

Antimony Recovery from End-of-Life Products and

2017-8-28  Abstract Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Anti-mony is produced from stibnite ore (Sb 2O 3) which is pro-cessed into antimony metal and antimony oxide (Sb 2O 3). The industrial importance of antimony is mainly derived
