Crystalline graphite is of natural floatability, so it mainly adopts flotation method for separation. Flake graphite also adopts flotation method for its better floatability, the graphite ore with a variety of gangue, also can use the combined process of gravity separation and flotation.
Application of graphite ore processing
Graphite ore beneficiation process mainly can be applied in the various graphite ore with different types of crystalline and graphite ore accompanied with silicate minerals such as Mica and Pyrite.
Features of graphite ore processing
Sinonine usually applying multi-stage grinding process to protect graphite flake from damaged. Applying multiple grinding and separation to meet the customers needs. Hydrocyclone can be used at the thickening stage, which keep the grinding density at 40% to 50% for better grinding efficiency. At the multi-flotation stage, No.2 oil, No.4 oil, ether glycol and butyl ether oil are the common foaming agents. As for collectors, mainly use kerosene, diesel oil, heavy oil, fat sulfonic acid ester, acid,etc. For graphite ore accompanied with heavy minerals, we usually adopt the process of mixing gravity separation and flotation. That is, separate the heavy minerals with gravity separation then process the heavy separation tailings with flotation method.
