Autoclave Circuit & Gold
Neutralized slurry from the pressureoxidation circuit is pumped to two parallel trains of eight CIL tanks for gold extraction and subsequent recovery of gold in a conventional Zadra elution circuit Suitable ancillary facilities are installed to supply flocculant, sulfuric acid, oxygen, lime, steam, and compressed air to the autoclave facilityCIL 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 processGold CIL & CIP Gold Leaching Process Explained CCD
