Graphite is an important non-metallic material, widely used in lubricants, refractory materials, batteries, casting, pencils, coatings and other fields. In actual production, each industrial sector has its own requirements for the purity of graphite, so it is necessary to use a relative graphite ore beneficiation process to purify it before use. Due to the large differences in the properties of raw graphite ore, there are also great differences for different graphite ore production processes. Among them, gravity separation, flotation, and electric separation are more widely used in graphite production.

Generally, crystalline and amorphous graphite ore is coarsely crushed by jaw crushers, and for medium and fine crushing, cone crushers or hammer crushers are used; wet ball mills and lattice ball mills are used for grinding; JJF and XCF are

commonly used in graphite flotation. Type, XJB type flotation machine; Graphite ore beneficiation dehydration commonly used hydrocyclone or belt filter.
