Fluid environments cannot be provided simultaneously by the stirring mechanism of a flotation cell (dobby and finch, 1986). the flotation column has no stirring device, and thus, the mixing effect of pulp and reagents is particularly important for the subsequent separation process (clayton et al., 1991; harbort et al., 1994; liu et al.,.

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.
Vertical baffles decrease the froth’s residence time and radial launders decrease froth transit time. froth crowders for both the wemco and xcell flotation cells direct the slurry flow from the centre of the flotation cell to the periphery launder, which decreases froth residence.
