    Recovering Gold through the Froth Flotation Process

    Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However one of the most interesting methods is froth flotation.
