    How Can You Separate Gold From Mercury? Global

    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. Aqua Regia is a mixture of hydrochloric acid and
