Flotation Developments & Best Practice International Mining

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 time.

Column Flotation Cell Baffles

The improved performance of column flotation over conventional flotation is not without draw backs. It is well known that axial mixing and coalescence of air bubbles results in a decrease in efficiency of separation in flotation columns. Axial mixing is the vertical mixing which occurs along the axis of the column (see Figure 1).

An induced static flotation (ISF) cell has an inlet chamber, a plurality of gasifiion chambers, and an outlet chamber. Contaminated liquid enters the inlet chamber, passes through the gasifiion chambers, and exits through the outlet chamber. Gas bubbles are introduced into the bottom of each gasifiion chamber and attract suspended contaminants and/or oil as they rise.
