Amalgamation: Using Mercury to capture fine gold,

2014-6-22  The gold literally is dissolved into the mercury. This allows the collection of very small sized particles of gold. At the end of the operation the mercury and gold amalgam are collected after which the two are separated, and the mercury recycled. Now larger gold and nuggets will not be completely converted (except over a very long time) and only a thin coating of amalgam forms. However, large nuggets should not be captured with mercury, it should be saved

Gold USGS

2001-7-31  Extraction of gold and other precious metals from their ores by treatment with mercury is called amalgamation. Gold dissolves in aqua regia, a mixture of hydro-chloric and nitric acids, and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide process that is used to recover gold from low-grade ore.
