How Is Gold Formed? Origins and Process

 · Gold is a chemical element easily recognized by its yellow metallic color. It is valuable because of its rarity, resistance to corrosion, electrical conductivity, malleability, ductility, and beauty. If you ask people where gold comes from, most will say you obtain it from a mine, pan for flakes in a stream, or extract it from seawater.

Extraction of Gold

Extraction of Gold

The extraction of gold by the cyanidemethod is of great technical importance. It is effected by lixiviation with a solution of potassium cyanide, the gold being precipitated either by addition of zinc or electrolytically. The process was suggested by Mac Arthur and Forrest in 1385, and is based on the wellknown solubility of gold in potassiumcyanide solution, a phenomenon said to have been ...
