Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.
Stage 3: hashing. The hashing stage (corresponding to metal extraction and recovery stages) is a little more complex for gold ores, as the optimal process flowsheet selection choice is heavily dependent on a good understanding of two fundamental geometallurgical parameters, the gold mineralogical associations, and the gold particle …

After heat-treating the resulting slurry, miners could separate the mercury and gold for processing. Even artisans have used mercury and gold to create stunning effects. Ormolu – a type of mercury-gilding – involves coating a piece (usually porcelain) in an amalgam, then using extreme heat to burn away the mercury, leaving a layer of gold.
