Gold Flotation - Mineral Processing and Metallurgy

GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of base-metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.

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. Froth flotation works by exploiting the hydrophobic properties of gold molecules.
