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.

However, extracting gold from quartz vein gold ore is a meticulous process that requires careful planning and execution. 1. Cyanide gold extraction includes crushing, leaching, filtering, adsorption, elution, etc. The first step in the method is crushing the quartz into small pieces. This can be done using a jaw crusher or a mortar and pestle.

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where ...
