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

1130;The Merrill-Crowe process for gold recovery is generally performed near ambient conditions. Gold content in Merrill-Crowe process solutions is often between 0.5 and 10 ppm . Treatment by this process generally requires a clarified solution that is deaerated. Deaeration reduces zinc losses and unwanted reactions.

201421;The Merrill–Crowe process is a cementation process involving classic redox reactions. 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-leaching. It has also been used on eluates from carbon stripping …

Abstract. This paper is a brief overview of the role of inducing the nucleated precipitation of copper and cyanide in a flashtube serpentine reactor, using sodium sulfide as the precipitate and sulfuric acid as pH control. The results showed that pH had a great effect on copper cyanide removal efficiency and the optimum pH was about 3 to 3.5.
