Merrill–Crowe process - Wikipedia
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 Merrill). The solution is separated from the ore by methods such as filtration(e.g. vertical leaf type clarifier filters…

Merrill Crowe Flowsheet Zinc Precipitation on Gold ...
Merrill-Crowe process has some advantages over the carbon adsorption process in cases of high metal concentration like ore containing significant amounts of silver; high silver to gold ratios. As gold ore grades increase and silver content goes over 30 ppm, Merrill-Crowe process is a good option. (Gold Metallurgy, 2011).
