A metallurgical process for extracting gold by leaching gold from pulverized ore with a cyanide solution. Gold is subsequently adsorbed onto activated charcoal for later recovery. CIL plants add carbon to the ground ore pulp during the leach cycle, and hence are better suited to ores that haveponents that would prematurely bind to the gold.
