  • Using Carbon in Pulp (CIP) for Gold Recovery MiningMet

    On a CARBON IN PULP (CIP) operation one typically achieves an upgrade ratio of between 1000 to 1200. The upgrade ratio is the ratio of the feed gold tenor, gold in solution, to the loaded carbon grade, g/t gold adsorbed onto carbon. A CARBON IN PULP (CIP) operation will typically be designed to have a stage residence time of one (1) hour.
