Metallurgical process
Research shows the extraction efficiency of this process to be 75% to 76%. The dissolved gold is adsorbed onto activated carbon, and the 'loaded carbon' in each circuit enters the carbon treatment section where the gold is eluted from the carbon. The carbon then returns to the CIL circuit via a regeneration kiln. Once the gold has been eluted, it undergoes a process called electrowinning ...
