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. The specific design criteria for these ...
On the other hand, with a Merrill-Crowe process, the total capital cost is solely a function of the initial flow rate. Operating costs vary in the CIP plant according to the grade of gold in the leach liquor. This cost does not vary with the Merrill-Crowe except in the case of zinc usage which increases with higher input concentrations.

It is also known as the Merrill-Crow process by its founders, C. W. Merrill, USA, who started it, and T. B. Crow, from South Africa, who made some necessary changes (Miller, 1981). How is zinc extracted from its ore zinc sulphate or zinc carbonate. Answer: Zinc is obtained by roasting sulfide ore and from carbonate ore, we use a calcination ...
Merrill–Crowe process explained. 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 …
