        The countries producing graphite in the world mainly include Russia, China, India, North Korea and Sri Lanka. China's main producing areas are Heilongjiang, Hunan, Shandong, Inner Mongolia, and Jilin.

         

        The main beneficiation methods include flotation, re-election, wet sieving, pulverization, etc. In order to obtain high-purity or high-carbon products, chemical beneficiation and purification are also required.

         

        Flotation The main method of graphite beneficiation. For crystalline graphite ore, kerosene, diesel, heavy oil, sulfonate, phthalate, phenol, carboxylic acid are often used as collectors, pine oil, 1,1,3,3-triethoxybutane, An ether alcohol or the like is used as a bubble agent. The process flow is multi-stage grinding, multi-stage sorting, medium-mineral return, returning one by one or returning one after another. For cryptocrystalline graphite ore, commonly used kerosene, coal tar, as a collector, eucalyptus oil, pine oil as a foaming agent, sodium carbonate as a regulator, water glass and sodium fluorosilicate as inhibitors.

        Flotation The main products of graphite beneficiation are: crusher, energy-saving ball mill, magnetic separator, flotation machine,
