Antimony is a chemical element with symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl.
The extraction of antimony from stibnite was studied by smelting it in the presence of zinc oxide, sodium carbonate, and a small amount of sodium hydroxide.
