Research on Beneficiation Process of Flaky Graphite

Large flake graphite have widely used in many fields because of its superior physical and chemical properties. Large scale flake is easily destroyed in processing. This article introduces the recent progress in beneficiation technologies for protecting large flake graphite from two aspects:grinding media or machine and flotation process. The problems existing in the current flotation process are analyzed in detail, and the direction of further study are put forward.
