Abstract
A apparatus system is disclosed for time beneficiation of kish to produce coarse high purity graphite wherein a concentrate containing at least about 90% carbon is formed, treated with a dilute acid solution, and the pulp then subjected to an adjuvant-assisted attrition to form a novel synthetic flake graphite of 99+ wt. % carbon with at least 70% of the mass retained on +100 mesh, and an overall recovery of graphitic carbon from the feed of greater than 85% by weight.
