Antimony (Sb) is a brittle, silver-white, shiny, and important metal with a specific gravity of 6.68 g/cm 3 and a melting point of 630 °C, which is widely used in modern industrialized societies today. Sb metal breaks too easily to be used on its own, but it gives strength, hardness, and resistance to corrosion to alloys [1].Sb is rarely found in its native form due to its strong …

Antimony Metallurgy
In 1963, China successfully developed the process of antimony sulfide concentrate volatilization smelting in blast furnace, which was a new technology for antimony production. In 1986, China developed the chlorination–hydrolysis process that directly uses antimony sulfide ore to produce antimony xide (antimony white).
