    OverviewSee also

    The Merrill–Crowe Process is a separation technique for removing gold from the solution obtained by the cyanide leaching of gold ores. It is an improvement of the MacArthur-Forrest process, where an additional vacuum is managed to remove air in the solution (invention of Crowe), and zinc dust is used instead of zinc shavings (improvement of Merrill). The solution is separated from the ore by methods such as filtration(e.g. vertical leaf type clarifier filters

    The hybrid Merrill-Crowe/CIL circuit is an interesting variant that was adopted at Mt. Muro. This included a single stage of thickening after the gold leach with the overflow routed to Merrill-Crowe and the underflow to CIP. The rationale for the use of this circuit was the poor settlement characteristics of the oxide solids that would have led to a requirement for large thickeners or filters ...
