Antimony - Wikipedia

Antimony is a chemical element with the syol Sb (from Latin: stibium) and atomic nuer 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.

Gold Smelting & Refining Process

Refining Gold. Refining processes are employed to improve the gold product quality. There are several types of refining procedures employed, but some of them are selected according to the daily production. It is important to mention that the gold purity is variable according to the process employed and the worker’s experience.
