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.
Flotation is considered to be the most cost effective method of concentrating refined gold and is often used in conjunction with flotation and/or cyanidation. Working principle of flotation cell The impeller is rotated by V belt of motor and produces negative pressure by centrifugal function.

Because of the surfactant, the gold is repelled by the water into the air bubbles, which rise to the top creating a bubbly gold foam. The froth is removed from the top of the cell creating concentrated gold, while the flotation tailings at the bottom of the tank are disposed of. Thanks to froth flotation, miners and refiners are able to ...
This machine was of the cell to cell pulp flow design and used a quarter turn flat belt line shaft drive. 1934 A portable gold placer machine designed to recover fine gold by flotation. Many similar mills were sold for gold recovery during the great depression. 1933 First steel tank low head, low level flotation machine. It had an individual ...
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.
