Flotation
Industrial flotation plants contain a series of flotation cells, chemical addition points and re-grind mills designed to maximize pentlandite recovery and the nickel grade in the concentrate. Two types of cells are used: mechanical cells and column cells. 15.3.1 Mechanical Cells. The flotation cell illustrated in Figure 15.3 is a

Scale-up of Flotation Processes
exposure in mineral flotation typically increases the recovery of component to be collected with the froth, but leads to product grade deterioration. Therefore, determining the correct arrangement and size of the flotation cells based on batch and pilot test results (scaling-up) is extremely important for the overall results.

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.
