Gold CIL CIP Gold Leaching Process Explained CCD

Jan 02, 2013  CIL stands for carbon-in-leach. 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 carbon-in-pulp process.

Valves for gold production with CIL, CIP or CIC circuits ...

In the CIL circuit, cyanide and oxygen are added to the slurry, resulting in gold being dissolved from the ore. Activated carbon is then fed into the process from the opposite direction, against the slurry stream, and as it moves through the CIL tanks, dissolved gold adsorbs onto the activated carbon.
