Application Note Cyanide Leach Process - pH

Cyanide leaching is typically followed by an extraction step to remove the solubilized gold from solution. Carbon adsorption is often used to isolate the aurocyanide complex. This is typically referred to as CIP (Carbon In Pulp). Sometimes the leaching and carbon adsorption steps are combined. This is referred to as CIL (Carbon In Leach).
