1 Froth Flotation Fundamental Principles

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.

Froth flotation Wikipedia

Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation

In the flotation tests, the hanging cell flotation machine FGC(535) (Wuhan lock grinding equipment manufacturing Co., Ltd, Wuhan, China) was used, with the rotating speed of 1750 r/min. In each test, the muscovite 10.00 g was placed into the flotation cell, adding appropriate distilled water to adjust the pulp concentration to 13.33%.

G Flotation Concentrate
Process IntroductionApplicationProcess DescriptionProcess FlowsheetThe flotation method is a widely used technique for the recovery of g from gcontaining copper ores, base metal ores, coppernickel ores, platinum group ores and many other ores where other processes are not applicable. Flotation is also used for the removal of interfering impurities before hydrometallurgical treatment, for upgrading of low sulfide and refractory ores for further treatment. Flotation is considered to be the most costeffective method for concentrating g. Flotation process m Chat
