Gold CIL CIP Gold Leaching Process Explained CCD

CIL stands for carboninleach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carboninpulp process.
