This allows for the subsequent REE mineral recovery processes to function in an economically efficientSize Reduction and Energy Requirement ScienceDirect,The mechanisms of size reduction during crushing and grinding are different. The chief difference is that in crushing operations the size reduction is more by compression and impact and less by attrition while in grinding; the forces of attrition are much greater.
