    Cyanidation. More gold is recovered by cyanidation than by any other process. In cyanidation metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete the gold-bearing solution is separated from the solids. With ores of higher gold content greater than 20 grams of gold per tonne of ore cyanidation is accomplished by vat leaching which involves holding

  • Gold Processing Mining And Concentrating Britannica

    Amalgamation is accomplished by passing a slurry of ore over copper plates coated with mercury by mixing a slurry of ore and mercury in a cylindrical or conical vessel called an amalgam barrel or by grinding the ore in a ball rod or pebble mill to free the gold from the mineral matrix and then adding mercury to the mill and continuing grinding until the gold has dissolved in the mercury.
