Process Flow-Sheet for Gold and Antimony Recovery from Stibnite ... in order to increase the economical convenience of the subsequent gold extraction. …


An 80 per cent gold recovery was made by the method of treatment described. It is generally known that antimony can be readily volatilized, and by roasting stibnite (Sb2S2) in an oxidizing atmosphere, antimony oxide can be driven off and condensed. At the same time, anyone who has had experience with such roasting knows that it is a delicate ...

The process parameters for the extraction of antimony were optimized on laboratory scale by …


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.

achieves the greatest gold recovery at the lowest cost. Normally these two are mutually exclusive and some measure of compromise is required. The grade of gold in the orebody can be critical in establishing the process options. Maximum gold recovery can normally be justified for high-grade deposits, even though this usually means relatively high
