摘要： A system, apparatus and method for separating hard contaminates of a compound from softer elements using a milling process wherein particle size reduction if effectuated on the softer elements. The milled material is then subjected to particle separation devices to remove the larger particles thereby reducing the percentage of hard particles in the remaining compound. Additional milling and separation steps are used to hard material concentration to less than a predetermined threshold.
