It is widely known that the processes of ore concentration have large part of operating costs for ore processing at the concentration plant. Often processes of crushing and grinding of raw materials account more than 70 % of the total spending. The aim of the optimal mineral processing is to decrease these costs, one solution of this problem is to preconcentrate raw material, which allows to withdraw from the further processing more than 80 % of the material, which doesn't contain valuable component, or has its dumping grade.
