  • Hard Rock Mining Gold and Silver Ore and processing it

    In both methods, gold and silver is accumulated in the cyanide leach solution. The gold and silver bearing liquid, called pregnant solution, is separated from the ore by various drainage and filtration processes. The most common methods to remove the gold and silver involve activated carbon, or zinc precipitation.
