2022.11.19 Among various beneficiation techniques, froth flotation is more suitable for treating fines and naturally hydrophobic ores. Flotation is a surface phenomenon based on the surface hydrophobicity of the mineral surfaced to be separated [2,3,4]. Due to the natural hydrophobicity of graphite, this technique is adopted for beneficiation.
