Buy Used Merrill Crowe

A.M. King offers complete Merrill Crowe systems and individual process components for efficient gold and silver recovery from cyanide leach solutions. The Merrill–Crowe method—an industry-standard precipitation process—removes dissolved oxygen via vacuum de-aeration before adding zinc dust to recover precious metals.

Our inventory consists of skid-mounted precipitation plants, vacuum leaf filters, and de-aeration towers, all used to clarify, de-aerate, and precipitate with precision. These compact units, including portable setups with flow capacities from tens to thousands of gallons per minute, are ideal for both pilot and full-scale operations.

We carry modular systems including pre-assembled pumps, piping, vacuum columns, zinc feeders, and integrated filter units—aligned with recognized configurations from FLSmidth and other industry leaders.

Whether you're building a gravity-flow settling plant or a full precipitation circuit, A.M. King delivers reliable precipitation system components, used Merrill Crowe plants, and support equipment ready to reduce setup time and improve recovery rates.
