This document provides a general overview of the use of cyanide in the gold . The strength of bulk cyanide reagents vary from 98% for sodium cyanide .. CIL (carbon-in-leach) tanks or into separate CIP (carbon-in-pulp) tanks after leaching.
the mechanism of gold adsorption is important because the CIP/CIL . Activated carbon is essentially carbon, it is inert, and so it carries no charge (unlike Na .. In the adsorption of gold cyanide and other adsorbates by activated carbon in CIP.
During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution.
