The advent of carbon-in-pulp in the early 1980s was probably the single most important technological development over the past hundred years. The recovery of gold from refractory ores has also steadily increased over the past 20 years, largely a result of circumstance and necessity, as the easier free-milling gold ores have been depleted.

Styles of centrifugal pumps used in pumping carbon to minimize carbon
Attrition of activated carbon in either the carbon-in-pulp (CIP) or carbon-in-leach (CIL) method of gold extraction can lead to, at the least, loss of expensive carbon that has to be made up, and at the worst, loss of both the carbon and any gold that was attached to it. Carbon attrition therefore represents a significant factor in both the …
