The pyrometallurgical methods include precipitation smelting and reduction smelting. Sulfide concentrates serve as the raw material for precipitation smelting, which is based on the replacement of antimony in the sulfide by iron: Sb 2 S 3 + 3Fe ⇄ 2Sb + 3FeS. The iron is introduced into the charge as scrap, and the smelting is carried out in ...

The most common source of antimony is the sulfide mineral known as stibnite (Sb 2 S 3), although it sometimes occurs natively as well. Antimony has numerous applications, most commonly in flame-retardant materials it also increases the hardness and strength of lead when combined in an alloy and is frequently employed as a dopant in ...

1. Introduction. At present, most antimony smelters still adopt the volatilization process in blast furnace to extract antimony trioxide (Froehlich et al., 2017), and reduce it by coke in a reverberatory furnace to metallic antimony (Anderson, 2012).This process chain, however, has drawbacks, such as low efficiency, high energy consumption (around 3.6 × 10 7 kJ/t Sb) and high operation ...
