• Increasing the Fine Flaky Graphite Recovery in Flotation

    Flaky graphite can be easily purified by flotation due to its high natural hydrophobicity 6 7 .Generally the flaky graphite ore was purified via multi-stage grinding-flotation (as shown in Figure 1a) to prevent the graphite flakes from being destroyed during the following regrinding and a large amount of middling was naturally produced in the process 8 9 10 .

    This invention concerns a method of beneficiating graphite to a higher purity level by dislodging the impurities from graphite by attrition preferably in an attrition cell which has at least one set of opposing pitched impellers. A pulp is formed preferably essentially consisting of a flake graphite attrition adjuvant water in a ratio of 1 2 0.8 to 10 and this pulp subjected to attrition in an

    2020-12-1 · The purification was carried out through three steps i.e. Paths A B and C as shown in Fig. 1.Initially 100 g of 10 H 2 SO 4 and 2.5 g of 30 H 2 O 2 were mixed with 10 g of graphite powder and reacted for 1 h in an ultrasonic bath with stirring at room temperature. Then the mixture was rinsed several times with distilled water at 60 °C to obtain graphite at neutral pH 7 and dried
