Gold Smelting & Refining Process
28/02/2016 When the charge is taken high temperatures lead oxide is reduced and metallic lead is produced. This metallic lead in liquid state traps gold and silver. As slag and metallic charge have different densities, lead and precious metals go to the bottom of the crucible and the slag floats. In other words, lead reduces the losses of precious metals into the slag. The

Extraction of Gold
The extraction of gold by the cyanide-method 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 well-known solubility of gold in potassium-cyanide solution, a phenomenon said
