Cyclones are used to separate particles in a liquid suspension This can be challenging to operations as the pressure flow and ore grade concentrations often vary Our advanced process control solutions account for changes in cyclone control and can increase product recovery and reduce grade variation

The control system of claim 1 with said ball mill grinding circuit being operative in a reversed arrangement such that the new ore material passes to said production cyclone before passing to the ball mill grinding device and said actual load material solids flow is the underflow from said production cyclone

Fewer mills are however easier to control and capital and installation costs are lower so the number of mills must be decided at the design stage The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs which has in turn made many low grade high tonnage operations such as copper and gold ores
