flotation of natural graphite flakes

Research progress of flake graphite flotation reagents ...

2021-9-1  Flotation is usually used for separation. Since flake graphite can only be obtained from ore, it cannot be synthesized manually and cannot be recovered once damaged, so the protection of flake graphite should be paid attention to in flotation. Besides the suitable flotation process, the choice of flotation agent is also very important.
