Amalgam method - Amalgam method
|
Also known as the mercury process. A smelting method that takes advantage of the fact that gold and silver tend to form amalgams with mercury. The ore is crushed with mercury to form an amalgam, which is then poured over a copper plate with an amalgamated surface, capturing the gold-silver amalgam. The mercury is then removed by distillation. The recovery rate is low, so this method is no longer used. Source : Heibonsha Encyclopedia About MyPedia Information |
