Since 1972, KCA has fabricated portable or modular carbon adsorption, carbon desorption, carbon stripping, and Merrill-Crowe plants. KCA’s plants have earned an outstanding reputation for quality, simplicity, ease of start-up, and fail-safe operation. Modular plants can be constructed for gold operations treating up to 4,000 tonnes of ore per day. Above that size, plants are built on-site.
