    Historically, the process for recovering freemilling silver was very like that for recovering freemilling gold. Some rich silver ore deposits, however, feature the metal in a more complex mineral, like a sulfide, in which form the silver is not amenable to extraction by simple amalgamation. Over the years, miners and metallurgists devised methods for treating silver .

  • Merrill–Crowe process

    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 MacArthurForrest 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).
