Gold Amalgamation - Mineral Processing Metallurgy

Amalgamation Explained. Gold absorbs mercury, forming a solid solution which may contain as much as 13 atomic per cent, of mercury. Be­yond this, an inter-metallic compound containing gold or mer­cury in solution (or a second solid solution) is formed, which contains 17.5 atomic per cent, of mercury.

nature. Where amalgamation plants could recover about 60% of the gold present, cyanide could recover about 90%. Because of the improved recovery, many of the old tailings piles from other processes have been economically reprocessed by cyanide leaching. Cyanide is as close to a “universal solvent” for gold as has been developed.
