Antimony Fuming, Smelting & Refining Plant

Metalcess Intelligent provide the complete system for Antimony smelting and refining to produce 99.99% Sb ingot from Antimony (Sb) Ore, Concentrate, Dust, and Ash. The main technological process is fuming-reduction smelting and refining.

RAW MATRIAL

Antimony (Sb) ore, Antimony concentrate, Antimony sulfide ore, Antimony oxide ore, Antimony furnace dust, Antimony ash

Output Quality

Semi-finished product: Antimony white (Antimony oxide) (Sb2O3≥ 99.5%）

End product: Antimony ingot (Sb≥ 99.9%）

Main component: Sb ≥ 99.85wt%;

Impurity limits: As ≤ 0.05%, Pb ≤ 0.08%, S ≤ 0.02%;

Fuming of Antimony

Fuming of Antimony

Owing to Antimony's low boiling point, Antimony sulfide will be sublimated into metallic Antimony at high temperatures, which is rapidly oxidated into Antimony trioxide (antimony white) and further collected from fuel dust. This Antimony white exhibits higher purity with minimal impurities, which is very favorable for the subsequent reduction and refining processes to get 99.9% purity metallic antimony. Thus a fuming furnace for antimony ore smelting and antimony slag recycling is required.

The fuming furnace for Anotimony: blast furnaces, reverberatory furnaces, cupola furnaces, and open-hearth furnaces.

Reduction Smelting and Fire-refining

Reduction Smelting and Fire-refining

The antimony trioxide powder produced by the fuming furnace is collected from the surface cooler and bag filter. It is an intermediate product containing a considerable amount of impurities such as metal oxides and non-metal oxides. The most common impurity oxides are PbO, As2O3, and small amounts of Cu, Fe, and S. Therefore, antimony trioxide needs to be reduced and refined in a reverberatory furnace to produce high-purity antimony.

At high temperatures, antimony trioxide will be reduced to metallic antimony and sink to the bottom of the furnace. Some antimony will still volatilize into the flue dust and enter the flue gas treatment system.

Refining processes include sulfur addition for iron removal and alkaline refining, etc. This process is currently mainly achieved through reverberatory furnaces in China.
