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
Vein deposits have complex geometry, are narrow and are selectively mined underground in Sri Lanka. Amorphous graphite is mined underground, mainly in China, using methods similar to coal mining. The most commonly used beneficiation method for flake graphite is flotation, while acids or alkalis may be used to leach out impurities from concentrates.
