Mechanical Fine Gold Flotation Cell. Initially our interest arose from a need, in the laboratory, to pre-concentrate a sample prior to analysis, either to enhance the confidence in the analysis or to facilitate morphological characterisation. A Wemeco Fagergren machine with a 2 litre cell was used. Recoveries were somewhat inconsistent but it ...

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.

Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold's hydrophobicity. This mixture is placed into a large tank filled with distilled water.

Most methods of water-based gold extraction are dependent on gold's lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).

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.

In this case the laboratory mill should be set-up for 1.0 kg of sample as it is practical and best to mill the same mass of sample that will be used in the subsequent flotation test. The LabTech Essa flotation cell has a live volume of 2.0 l. To float at between 30 and 35%

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
