  • Merrill–Crowe processWikipedia

    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).
