The primary purpose of a flash flotation cell is to remove liberated and fast floating valuable mineral particles before they are overground to a finer particle size and then report to the cyclone overflow where they are more difficult to recover in a downstream conventional flotation circuit Gaudin, Groh and Henderson, 1931 Morris, 1952.
Design considerations include the hole size, distribution of the holes to ensure water is spread across the entire surface of the flotation cell, placement of the system at an appropriate distance above the cell lip, and most importantly, the robustness and ease with which it can be maintained as the quality and cleanliness of the water used for froth washing in most plants is often poor which can lead to frequent

MAC flotation cell uses single stage vertical design and laminated configuration, which covers a small area. It uses PLC automatic control, so it is easy to control the level. The deinking effect is significant Table 11.12.
The primary purpose of a flotation cleaning circuit is the separation of valuable hydrophobic minerals from non valuable minerals. Non valuables include hydrophilic gangue, mildly hydrophobic minerals such as iron sulfides, and minerals lockedposite particles.
Practical design considerations such as flotation time, type, number and size of flotation cells, and the means of froth transport are all important and appropriate test work can guide decisions on all these factors.
