To avoid the adverse effects of antimony on gold extraction, a clean production process for removing and recovering antimony from refractory gold ore is proposed. The complete process flowsheet is shown in Fig. 2. First, the antimonial refractory gold ore is leached in alkaline sodium sulfide solution.

A two-stage roasting process, similar to that used for arsenic sulfide ores, can also volatilize antimony oxides and prevent adverse reactions such as the production of metallic antimony, which can coat the surface of gold particles (Nagy et al., 1966) or the formation of silver glasses in high-silver ores (Matsukawa and Sakai, 1956).

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) …
