refining antimony from stibnite - larteinarte

Stibnite (Sb 2 S 3) is an abundant antimony bearing mineral and thus it is the main source for the production of pure antimony trioxide and/or metallic antimony. The conventional technology for the production of metallic antimony from stibnite concentrates is primarily by oxidizing roasting to convert the stibnite into volatile antimony oxide ...

Antimony - an overview | ScienceDirect Topics

The most significant use of antimony is the production of antimony trioxide for flame retardation (ATSDR, 1992; Butterman and Carlin, 2004). Antimony trioxide (+ 3 antimony), a white powder, is the single most important economic form, used primarily as a fire retardant. It is a stable substance that is not volatile and dissolves in water slightly.

Antimony trioxide is the chemical compound with the formula Sb2O3. Antimony trioxide is an amphoteric oxide, dissolving in alkaline solution to give antimonites and in acid solution to given a range of polyantimonous acids. It can be readily oxidized to antimony pentoxide or other antimony(V) compounds, but is also easily reduced to antimony.
