Sulfosalts

Sulfosalts

Sulfosalt is a type of mineral that contains semimetal elements such as antimony, arsenic or bismuth, which substitute for the metal ions and bond with the sulfur, unlike in sulphides where they substitute the sulfur positions. The main antimony-lead-silver sulfosalt minerals include boulangerite, jamesonite, bournonite, tetrahedrite, and andorite.From: Advances in Raw Material Industries for Sustainable Development Goals [2020], Sulfur isotopic characteristics of the Zhaxikang Sb–Pb–Zn–Ag deposit in southern Tibet [2021]

Enargite and tennantite are part of the sulfosalt minerals’ class. Sulfosalt minerals differ from sulphides in that semimetal elements such as antimony, arsenic or bismuth in sulphides substitute the sulphur positions, but in sulfosalts they substitute for the metal ions and bond with the sulphur.

The pyrometallurgical roasting of sulﬁde ores and concentrates, which commonly incorporates considerable amount of sulfosalts, is one of the most important pre-treatments in the production of metals and chemicals from various raw materials. Most sulfide ores, concentrates, and tails in general tend to oxidize in air, and these reactions are exothermic (Dai 2016). Pyrometallurgical oxidation roasting of sulfide ores involve gas-solid exothermic reactions, and the process valorizes ore concentrates for the subsequent metallurgical processing. In addition to the oxidation roasting that includes dead and partial roasting decomposition and sulfating roasting are also widely used pyrometallurgical pre-treatment processes.
