Column Flotation Cell Baffles

Nov 12, 2017 Conventional froth flotation machines cannot produce an acceptable product from such material in a single stage of flotation, and even flotation columns often have difficulty cleaning this type of feed. Theoretical Discussion. Horizontal baffles, such as those described in this paper, are a compromise between the regular column and the packed ...

A study of a plug flow model for flotation froth behaviour

Mar 01, 1978 In order to observe the effect of various mechanisms on the gradients of mineral concentration in the froth, experiments were performed in a flotation cell using a deep froth phase where transverse motion of the froth was reduced to a minimum. The variables chosen for study include gas rate, baffling of the froth and product removal rate.

A Review of Flotation Physical Froth Flow Modifiers

Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the froth must travel increases with an increase in the ...

the use of a froth baffle previously suggested by Moys (1979) was tested in a laboratory mechanical flotation cell. Results indicated that a froth baffle has a profound effect on both recovery and grade. The presence of a froth baffle resulted in increased grade at the expense of recovery when compared to an un-baffled froth.
