A Comparison of Production Routes for Natural Versus

The mined natural graphite ores can be milled to liberate the gangue material, optimally with minimum size reduction below the most profitable range (100–600 micron) for the natural flakes. The liberated graphite particles are naturally hydrophobic, and therefore, can be subsequently floated with suitable oils at optimized pH conditions .
