Antimony Production from Domestic Stibnite Ores via

production method for antimony production if the process can be optimized to work with high metallization ratios In this method antimony can reduced in one step Sulphur is decomposed from stibnite and interacts with iron then a matte phase, mainly consists of FeS, is obtained over the metallic antimony The main reaction of Niederschlag 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 (Sb 2 O 3ANTIMONY PRODUCTION BY CARBOTHERMIC Amongst these, stibnite as a predominant ore alongside cervanite contributes the major portion of the global antimony supply3 Traditionally, pyrometallurgical methods have been commercialized for the extraction of Sb from stibnite This method involves a roasting–volatilization process in a blast furnace leading to antimony trioxide productionLeaching of Antimony from Stibnite Ore in KOH

Extracting antimony from high arsenic and gold

Antimony production involves hydrometallurgy and pyrometallurgy, the latter being still dominant The conventional extraction of antimony from stibnite and jamesonite involves a twostep pyrometallurgical process comprising volatilization roasting and carbothermal smelting (Ouyang et al, 2019; Tian et al, 2016)While the stibnite concentrated content is 75% (mass fraction, similarly hereinafter), FeO content is 16%, CaO content is 16%, the volatilization time is 60 min, the volatilization temperature is 1673 K, low melting point slagging and nonblowing operation are necessary, the primary volatilization rate of antimony from stibnite concentrate is Extraction Process of Antimony from Stibnite by A circulatory hydrometallurgical process: ferric trichloride (FeCl 3) leaching of antimony sulfide (Sb 2 S 3) (production of Sb by replacing it with iron) followed by membrane electrowinning of ferrous chloride (FeCl 2), was developed to cleanly extract Sb from stibniteFirst, Sb was leached (leaching efficiency >98%), using FeCl 3 as leaching reagent, under the following optimum conditions Ferric chloride leaching of antimony from stibnite
