flotation circuit machine

In short, don't cut the air unless you have to and then do it for as short a time as possible. Add as much air as your machine (froth) REQUIRES. A flotation machine needs deep froth in order to allow time for unwanted mineral to drain from the froth bubbles back into the pulp.

The flotation circuit before the plant upgrade consisted of two banks of five 500 ft3 Wemco Cells roughers, two banks of ten 1.8 m3 3Denver Cells as first cleaners, two banks of five 1.8 m as second cleaners. The rougher and cleaner tails were sent to three 30 m3 Outotec Cells. Figure 6 shows the flowsheet of the new flotation circuit.

Idaho Lead-Zinc-Iron Ore: "The Flash Flotation Cell is removing direct from the grinding circuit over 70% of the total lead recovered in the entire plant. This phenomenal recovery is made by a Unit Flotation Cell installed between the ball mill and classifier, and a coarse high grade rougher concentrate averaging 65% to 70% lead is …

Modern flotation machines are high-intensity equipment designed to create very small bubbles and higher flotation rates. Smaller bubbles are generated by intensive mixing of pulps with air so that fast collisions between particles and bubbles take place.
