  • Major Mines Amp Projects Mining Intelligence And News

    The extraction process is by conventional heap leach using sodium cyanide as the leaching reagent. Recovery of gold and silver from cyanide solution is by zinc precipitation. The very high silver content of the ore makes this process more cost effective than a carbon-in-leach or carbon-in-pulp process.
