01 Graphite Flotation Method. Graphite has good natural floatability and hydrophobicity. Therefore, most graphite processing plants use the flotation method to purify graphite ore, that is, adding a series of flotation reagents to enrich the graphite ore in the gas-liquid interface to achieve separation from impurity minerals. Therefore, most concentrators …
