Stibnite, the antimony sulphide mineral, responds much better to flotation after being activated with lead nitrate. The theory generally accepted on activation is that the activating substance, generally a metallic salt, reacts with the mineral surface to form on it a new surface more favorable to the action of a promoter.

Antimony, a toxic metalloid similar to arsenic, is present at variable levels in most gold-bearing rocks. Antimony is soluble in the surface environment, so antimony (Sb) mobilization in mine waters is an environmental issue around gold mines. The Reefton gold mine was originally developed in gold-bearing quartz veins; Sb concentrations were low (<100 mg/kg) …

Testwork was undertaken to develop a flowsheet that would maximise gold recovery from an ore containing 3 g/t Au and high levels of arsenic. Treatment of the sulphide ore involves gravity separation, flotation, and cyanide leaching. A gravity concentrate is recovered within the grinding circuit before the ore is subjected to froth flotation.
