Abstract: Embodiments of the invention are directed to systems and methods for purifying graphite particles. Graphite flakes can be milled, and then separated into groups with different nominal sizes. The different groups of particles are purified according to optimized purification processes. Groups of purified particles with narrow size distributions are created using embodiments of the invention.
