2. The oxide antimony ore can refer to the above specification and should be reduced the price by the Sb content.
The pyrometallurgy technics process has been adopted on antimony concentrates to produce various antimony products, such as antimony oxide, antimony white(Sb2O3), and crude antimony(acicular antimony trisulfide).
