Cyanide Amalgamation Process Of Gold

Amalgamation Process of Gold - Mineral Processing & …

The amalgamation process, which has been widely used in a variety of forms from earliest times, depends upon the wetting and alloying of metallic gold and silver with mercury. Because of its high specific gravity and tendency to be collected by larger masses of liquid mercury or mercury-coated surfaces, this alloy, or amalgam, is readily separated from the lighter constituents of the ore pulp.

The process of extracting gold from ore is a multistep one, and historically it has involved the use of some dangerous chemicals, including cyanide and mercury. Cutting-edge extraction techniques have eliminated the need for these chemicals and made the process much safer. It's still too dangerous to try at home, though.

Gold amalgamation process in mz

AMALGAMATION IN MZ Whole ore amalgamation is used for primary gold. The ratio of 4-15:1 Hg:Au is estimated in whole ore amalgamation. In some countries you can find ratios of 50:1 (Indonesia) The process of amalgamation itself frees up to 60% of mercury into the atmosphere.
