introduction to open circuit in mining

Classifiers are mainly spiral classifiers and hydrocyclones. They are widely used for classifying ore sands in the close-circuit process together with ball mill in the dressing plant, or for classifying ore sands and fine silts in gravity concentrator, classifying the particle size of ore pulp in metal beneficiation process, and for desliming and dehydration in ore dressing.
