2016-9-26 Using a chemical solvent, usually cyanide combined with oxygen, the gold is extracted from the pulp inside these tanks; but it is still not pure gold. This process is known as carbon-in-pulp. The result is gold that is attached to carbon. The next step is to remove the gold from the carbon bonds. This is achieved by filtering and separating the
