About Gold CIP. Gold CIP is one of the methods of gold extraction by cyanidation. It is a carbon adsorption process of monovalent gold cyanide [KAu (CN)2] after the cyanide leaching of gold-bearing materials. CIP usually applies in flotation gold concentrate, high argillaceous oxidized gold deposit, mercury mixing, and gravity separation tailings.

Gold refining is the process of purifying raw gold of its impurities and unwanted elements like silver, copper, zinc and nickel. The goal of refining is to produce gold that is at least 99.5% pure, if not higher. Achieving higher purity levels through refining gives gold several important advantages. For one, higher-purity gold is less prone to ...

It has been said that gold was one of the first metals to be mined. As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated. Gravity was the first method developed to recover gold from ore. But, currently there are very few deposits left that contain ores ...
