Abstract

The enrichment of graphite present in siliceous deposits comprises concentration after large-scale exhaustion of the non-graphite material, with grinding. The 0.5mm ground fraction undergoes flotation with kerosene as collector, or electrostatic above 15 kV treatment. EMBODIMENT - Conventional flotation with kerosene as collector concludes the processing.
