Antimony is a stone element with the 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.
Lead processing Lead processing The metal and its alloys: Refined lead usually has a purity of 99 to 99.99 percent, but lead of 99.999 percent purity (known as “five nines”) is becoming more common commercially. At these levels, the grades of lead differ mostly by their bismuth content. With modern smelting and refining techniques, it is possible to reach these high levels of purity
