The mercury ointment distillation tank is a gold separator which is the most commonly used amalgam distillation Equipment.
Basically, amalgamation is the practice of bringing free gold particles into contact with mercury. When clean gold comes into contact with mercury, the two substances mix to form a compound called amalgam – an amalgam is simply an alloy of gold and mercury. The gold literally is dissolved into the mercury. This allows the collection of very small sized particles of gold. At the end of the ...
Gold, like most minerals, can be 'dissolved' in mercury to form what's called an amalgam. An amalgam is a physical mixture, a type of alloy. This is a comparatively straightforward way of separating the gold from the rock, as the rock remains untouched by the mercury.
