One-Step Extraction of Antimony in Low Temperature from ...
antimony in the world. Generally, the technologies for producing antimony mainly comprise pyrometallurgy and hydrometallurgy [1,2]. Pyrometallurgy routes for extraction of antimony typically contain roasting-volatilizing-reducing process, bath smelting-continuous fuming process  and direct smelting process [4,5].
Antimony sulfide contained in an antimony sulfide bearing ore, such as stibnite, is converted to high purity antimony trichloride by reacting the antimony sulfide bearing ore with a source of chlorine to form high purity antimony trichloride and sulfur or hydrogen sulfide as separable by-products. The high purity antimony trichloride may be hydrolyzed to form high purity antimony oxide.
