Roasting in Metallurgy Mineral Processing Metallurgy
Roasting to Eliminate Arsenic and Antimony. H. M. Howe, in explaining how this is effected, distinguishes three horizontal zones in the ore: the upper surface, where oxidation is only slightly hindered by sulphurous and sulphuric acids and by the products of combustion of the fuel; the middle layers where oxidation proceeds to a very limited ...

Extraction of Antimony Element Antimony, Sb, Metalloid
For roasting sulphide ores two methods are used, viz., simple roasting yielding mainly antimony tetroxide, and volatilisation roasting yielding mainly antimony trioxide. In the former, reverberatory furnaces are employed, the flue gases passing through a condensing plant for the recovery of any antimony trioxide that may be formed.

Antimony Statistics and Information
The natural sulfide of antimony was known and used in Biblical times as medicine and as a cosmetic. Antimony in its elemental form is a silvery white, brittle crystalline solid that exhibits poor electrical and heat conductivity properties. Commercial forms of antimony are generally ingots, broken pieces, granules, and cast cake.

Regents Chemistry Exam Explanations August 2015
Antimony and sulfur are both found in the mineral stibnite, Sb2S3. To obtain antimony, stibnite is roasted (heated in air), producing oxides of antimony and sulfur. The unbalanced equation below represents one of the reactions that occurs during the roasting. .
Pictures of the Mineral Antimony
Antimony occurs as an indigenous metal, but generally you find it the form of antimony (III) sulfide. It is from this that antimony is taken out for trading purposes by roasting antimony (III) sulfide to oxidize it and further reduction is done by combining it with either iron or carbon.
