    Amalgamation Using Mercury to capture fine gold

    Occasionally, the amalgamation process does not collect as much gold as anticipated. This type of result usually occurs when the formation of amalgam is inhibited due to poor contact between the gold and the mercury. This happens most commonly when the gold is very fine or when it is tarnished by a surface or film.
