Separation-Color Sorting

 This stage is the process of separating solids into two or more products on basis of their size. This can be done dry or wet. Neither crushers nor grinding mills are too precise in their size reduction job and a lot of size fractions are misplaced. In mineral processing practices two methods (screening and classification) dominating size control processes.
Separation devices are include Flotation tanks, thickeners, Separators, hydro cyclones, air cyclones, Scrapers, drum magnets, drum filters, filter presses, screens and air classifiers.
