extraction antimony site

Arsenic-containing antimony gold concentrate (As-Sb-Au ore) is an important raw material for antimony and gold extraction [1–3]. Antimony often exists in the form of stibnite and usually needs to be removed before gold extraction [4–7]. Zhang et al. [8] proposed a slurry electrolysis (SE) method to pretreat this As-Sb-Au ore.

The reaction mechanism is explained with the fact that various antimony species predominate in the solution at various chloride ion concentrations. At acidities below 0.5 M, antimony extraction coefficient is a second order function of the acidity, while at acidities above 0.5 M, antimony extraction coefficient is independent of the acidity.

Abundance of antimony in bulk samples has been determined in five selected coals, three coals from Huaibei Coalfield, Anhui, China, and two from the Illinois Basin in the United States. The Sb abundance in these samples is in the range of 0.11-0.43 {mu} g/g. The forms of Sb in coals were studied by sequential solvent extraction.
