    Carbon-in-Pulp. The introduction of activated carbon to recover gold from cyanide leach solutions in the last quarter of the 20th century had a breakthrough impact on the economics of gold ore processing, as the world gold industry entered a period of unparalleled expansion following the deregulation of the gold price in the mid-1970s.
