  • The Merrill Crowe Process vs. Carbon in Pulp-Process

    The classic method of recovery of gold and silver from cyanide solution was Merrill Crowe until the introduction of Carbon In Pulp (CIP) in the 1970’s. The CIP process indicated savings in CAPEX. This meant that lower grade ores could be economically treated than otherwise would have been the case.
