Optimizing the froth area of large mechanical flotation …
Froth removal in flotation can be affected by modifying the open froth area in the flotation cell, so that the modification has a direct effect on the metallurgical performance of the flotation cell. The effect of reducing the open froth area was evaluated in a large flotation cell, TankCell® e300, in operation at a copper concentrator.

Flotation Cell Impeller Types
Flotation Cells are provided with openings in the partition plates for by-passing the pulp from cell to coll without the pulp circulating through each hood feed pipe. In normal operation these partition gates are left closed; however, this arrangement is advantageous when large tonnages are fed to the flotation machine.
