Full-Scale trial of the REFLUX™ flotation cell
A 2 m diameter REFLUX™ Flotation Cell was fed at roughly 210 m 3 /h, equivalent to a flux of 1.9 cm/s, about twice the maximum rate used in conventional flotation cells. The coal feed slurry had 59–64 wt% head ash and nominal size range −0.100 mm (Sauter mean size 0.004 mm). The air, wash water and underflow rates were …

Flotation Cell
Improved metallurgical performance of column cells in iron ore flotation is reported and attributed to froth washing, which reduces the loss of fine iron minerals entrained into the froth phase (Dobby, 2002). The Brazilian iron ore industry has embraced the use of column flotation cells for reducing the silica content of iron concentrates.

Adjusting Pulp and Air Levels to Troubleshoot Flotation Cell Froth Movement
The first corrective reaction is to raise the pulp level or add air to the cells to quickly increase the overflow. As a band aid solution this is correct, but as the ultimate correction it is not. The purpose of the air is to provide the medium that the collector attaches and to provide a surface for the mineral to be floated away on.
