:: Selecting Flotation Cells: How Many and min

2018 4 24&ensp·&enspThe new thinking has expanded to also consider the froth carrying rate and emphasises the importance of selecting flotation cells with a froth handling strategy in mind. In many cases, the use of fewer, larger cells has been of benefit as it has allowed the designer to have less froth surface area and thus more stable froth when treating low
