    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
