With low gold grades (0.15–0.4 g t − 1 Au) and a poor liberation, this 3pc cell was able to produce a product (12% gold recovery) with the quality of a rougher flotation concentrate (13 g t − 1 Au). These results could not be attained in the conventional column cell operating under similar conditions.

The circulation of mineral slurry is reasonable, and gold froth flotation machine can avoid the disposition of coarse sand to the largest extent.
The main steps performed prior to the flotation process or froth flotation process is the crushing of rock minerals, grinding ore to a size change the amount of fine sand grains in order to liberate the metal to the separation process and to prepare the appropriate size to the next process.
Artisanal and Small-Scale Gold Mining Without Mercury. ... This froth is then scraped off to create a concentrate of gold and other hydrophilic minerals. Flotation creates high quality concentrates and is good at capturing fine gold. Flotation usually requires a substantial amount of capital investment. ...
Flotation is used in gold, mineral processing, copper, coal, to recover fine particles, typically finer than 0.5 mm. Chemical and physical attachment of the solid particle to the bubble, induced by the chemical reagents and conditioners would be a over simplified description of froth flotation.

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.
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).
