TWO STAGE GRINDING CIRCUITS readily allow for the advantageous use of a Mineral Jig or a Unit Flotation Cell to recover coarse freed minerals as soon as they come from the grinding mills. There is a marked advantage in maintenance by having the ball mill and rod mill of same diameter as shown in the above table for interchangeability of parts.

2020 12 8 circuits thus confirming its validity. The difference in the three simulated circuits was in the cleaning stages. Among other things the simulation shows that the best platinum palladium and rhodium recoveries could be obtained if the greatest cleaning capacity was situated in the secondary stage of the circuit.
