  • [PDF] Comparison of mechanical flotation cell and cyclonic

    Comparison of flotation performance between the flotation column and mechanical flotation was carried out to promote the grade and economic value of the graphite ore (15.40% ash content). The ash content of the concentrate of the mechanical flotation was 10.77% at the yield of 79.34%. In contrast, the yield of the concentrate of the column flotation was increased to 88.93% with 10.55% ash content.

  • Optimization of process parameters for producing graphite

    In some graphite concentration processes, its poor flotation selectivity is most probably caused by the cross-pollution effect between fine graphite and gangue minerals. On the one hand, the gangue minerals are quite fine and could be mixed into the flotation concentrate by coating on graphite surfaces, and on the other hand, the graphite

  • Flotation

    The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical operations

  • Recovery of Microcrystalline Graphite from Quartz Using

    Efficient beneficiation of microcrystalline graphite remains a challenge. Selective recovery of microcrystalline graphite from quartz using hydrophobized magnetite as magnetic seed is studied in this work. Magnetite was hydrophobized by the surface coating of sodium oleate. The hydrophobic agglomerates were then separated by magnetic separation.

  • Multi-Stage Flotation for the Removal of Ash from Fine

    The multi-stage flotation circuit is a continual process of pulp density reduction that results in the continual improvement of the flotation separation selectivity in fine graphite ore. The non-selective detachment process of multi-stage flotation circuits using the mechanical flotation cell led to a large loss of valuable materials.

  • Preparation of High Purity Graphite From Alkali Roasting

    An alkali roasting process, which consists of roasting with caustic soda, water washing and sulphuric acid leaching, has been found to be an effective method for graphite purification even at low roasting temperature. With this process, a flotation fine concentrate containing 87–88% carbon could be purified to about 99.4% carbon when roasted with 25% NaOH at 250 C and leached by 10% H2SO4
