Jan 23, 2012· Froth flotation is commonly used for the concentration of low grade graphite ore. There are mainly there beneficiation method to extracted the high grade graphite including mechanical flotation cell, column cell and bulk oil flotation. Three Graphite Beneficiation Methods cell flotation of graphite
Dec 20, 2018· Flotation reagents for graphite beneficiation process The commonly used collectors for flotation crystal graphite are kerosene, diesel oil, heavy oil, sulfonate, sulfate, phenol and carboxylate. The common foaming agents are 2 oil, 4 oil, pine oil, ether alcohol and Butyl ether oil, etc., the adjusting agent is lime and sodium carbonate, and the
Graphite is a natural floater. Flotation has become the accepted method of beneficiation of graphite . Flake graphite from disseminated deposits is difficult to concentrate, therefore, a number of processes have been evolved by different countries.
Due to the strong floatability of graphite, flotation is the most commonly used method of graphite beneficiation. Among them, crystalline flake graphite has the best floatability, followed by vein graphite; amorphous graphite has the poorest floatability 3,6,7,8,9,10. Therefore, flake graphite can be easily purified by flotation.
