How To Separate Gold From Mercury

How To Separate Gold From Mercury

1. Gold Au and mercury Hg are two separate metals. Therefore from pure mercury you cannot extract Gold. 2. Amalgamation is better suited to ores in which the gold occurs in the free and cores state. Fine particles of Gold are better treated by Cyanidation. 3. Gold dissolves in aqua regia.

  • Amalgamation Using Mercury To Capture Fine Gold Retort

    The gold literally is dissolved into the mercury. This allows the collection of very small sied 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.
