This document provides a general overview of the use of cyanide in the gold and silver recovery process and is not . The first step in ore preparation is crushing and grinding which reduces the particle size of the ore and liberates these . by introducing it directly into the CIL carbon-in-leach tanks or into separate CIP carbon-in-pulp tanks after leaching. The activated carbon adsorbs the dissolved metal from the leach slurry thereby concentrating it onto a smaller mass of solids.
