This will stratify the crushed aggregate by density making separation easier. Where the DMS occurs in the process can be important, the grinders or mills will process much less waste rock if the DMS occurs beforehand.
a. Reduction in size. b. Separation of particles of dissimilar physical nature. So the first step in ore beneficiation is size reduction causing libration. This is followed by separation of liberated particles as the second step in the process. These two steps are made to alternate to accomplish the desired end product most economically. 1.4.CRUSHING SCRUBBING GRINDING GRAVITY ,separation, leaching, flotation and pumping.
