The Merril-Crowe Gold recovery Process. The Merrill-Crowe gold recovery process removes precious metals from a cyanide solution by zinc precipitation. The pregnant solution is first clarified through filters such as horizontal leaf type clarifiers. By using a precoat system (with diatomaceous earth) an extremely clear solution can be produced.
process at the Homestake Mine in Lead South Dakota in 1897 [6]. In 1918, the vacuum de-aeration tank was in-troduced by T.B. Crowe and was incorporatedinto the Merrill process to make the Merrill -Crowe process. This was the removal of dissolved oxygen, which caused zinc passivation making it almost impossible to filter [8].
Merrill-Crowe Process For smaller tonnage, higher-grade operations, particularly those in which the concentration of silver is greater than gold, the process that yields the most favourable economics for gold (and silver) recovery is Merrill Crowe cementation. In this process, the .

Study of Merrill-Crowe processing. Part I: Solubility of zinc in alkaline cyanide solution. ... Eh-pH diagrams have been developed and used to predict regions of stability of zinc hydroxide, which may inhibit gold precipitation. The interaction between cyanide and hydroxyl ion activities to prevent the formation of zinc hydroxide is presented.
