To avoid the adverse effects of antimony on the cyanide leaching process used for the recovery of gold from refractory gold ore, a cleaner production process was proposed that would selectively remove antimony as sodium pyroantimonate. The process included three steps: 1) leaching of antimony from the refractory gold ore with sodium sulfide solution; 2) pressure …

Because of the rise in gold prices, some antimony ores should really be viewed as gold ores with antimony as a by-product. In this context, cyanide leaching is an obvious step in addition to gravity separation, and the most logical procedure here would be first to separate the antimony at natural pH and then to leach out the gold with cyanide.

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. ...
