Amalgamation Using Mercury to capture fine gold, retort

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.
