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.
However, the antimony element is more difficult to remove during the matte smelting process, accordingly, a large amount of antimony compounds may seriously affects the lining life of the pyrometallurgical system, and has a continuous negative impact on subsequent valuable metal recovery (Artzer, 2018, Selivanov et al., 2019). Thus, it is ...

Antimony (Sb) is naturally present in the earth's crust at levels of about 0.2–0.3 mg/kg (ppm), but these levels vary by location (Telford et al. 2008). It can be transported into streams and waterways from natural weathering of soil, as well as from anthropogenic sources (EPA 1979; Mok and Wai 1990). Antimony enters the environment during the …
