A froth flotation cell consists typically of a collection zone (or pulp zone) located below the feed particle point, and a cleaning zone, (or froth zone), above the particle feed point [26] (Figure 2). The collection zone is fed back-stream by the pulp pushed by the bubble swarm created by a gas sparger at the bottom of the flotation cell.

The wide variety of cells studied included a Bateman 3-m3 cell, Outokumpu 16-m3 conventional and 50-m3 TankCells, WEMCO 84, 120, 144 cells and WEMCO 144 with 164 mechanism and high-power motor. The gas phase properties of bubble size, superficial gas velocity, air holdup and bubble surface area flux were used in characterising these cells.

Outokumpu designed and manufactured a 100m3 flotation tank cell to scavenge the Agitair scavenger tailings. The 100m3 Outokumpu flotation tank cell was installed and commissioned in 1996 at a cost of BWP1.5 million. This allowed the recovery of slow floating nickel associated with pyrrhotite and pyrite minerals.
