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 …

A laboratory flotation cell designed by CSIRO Minerals and a cylindrical tank fitted with a Rushton turbine used as a flotation machine have been modelled. The impeller and cell geometries have been set up using multi-blocking and sliding mesh techniques. Complex two-phase flow fields within the cells are predicted.

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 …

In principle, the cell functions as a shallow flotation cell. As the air and pulp are hydrau-lically lifted to the top of the pulp recircula-tion well, the mineral laden air bubble has only to travel a short distance on its own to the froth overflow level.
