Flotation Cell - an overview | ScienceDirect Topics

In Mineral Processing Design and Operations (Second Edition), 2016. 18.5.1 Batch Flotation. The concentrate obtained from a batch flotation cell changes in character with time as the particles floating change in size, grade and quantity. In the same way, the concentrate from the last few cells in a continuous bank is different from that removed from the earlier cells.
