Multi-stage grinding & multi-stage flotation

Xinhai 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.

Gravity separation & flotation process

For graphite ore accompanied with heavy minerals, xinhai usually adopts 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.
