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.
