Primary and secondary processing of minerals and metals involves handling materials in particulate form of variable size, shape, chemical composition, and mineralogical composition. (A particle is simply defined as something that is small in relation to its surroundings.) Such complex process systems demand careful assessment of the nature of the feedstocks and quality of the products. In
