Gold Amalgamation Process Principles 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 mercurycoated surfaces this alloy or amalgam is readily separated from the lighter constituents of the ore pulp

Further Details
By the foregoing considerations the belief is confirmed that amalgamation is a physical rather than a chemical process The solubility of gold in mercury is almost negligible and the diffusion of the mercury into the gold forming a solid solution or intermetallic compound is a rather slow process unless the gold is very finely divided whereas the “catching” of the gold by the mercury
Further Details
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
