THE MERRILL-CROWE PROCESS The Merrill-Crowe process is a cementation process involving classic redox reactions. CE Normally it is applied to solutions generated either from a solid-liquid separation step downstream of a grinding and leaching operation, or from solutions originating from heap- …
Flowsheet. Merrill-Crowe zinc precipitation is the most commonly used cementation process for gold recovery, and consists of four basic steps (Figure 8.1): Clarification of the leach liquor; Deareation; Addition of zinc (and lead salts); and; Recovery of Zn/Au precipitate. The precipitate is then smelted to recover the precious metals.
