Effective desliming of froth flotation cell feed at Elk Run …
This paper focuses on the −½ mm cleaning at Elk Run Coal. The original circuitry incorporated desliming cyclones. Problems with slimes entrainment in the cyclone underflow (froth cell feed) resulted in poor froth cell selectivity. Laboratory test work led to the installation of high frequency desliming screens. Consequently, great improvement in cell performance was brought about …

Froth flotation process and its application
The components of a flotation system are (figure 1): Cell: A container that contains an impeller and is competent to retain the solids in suspension. It also provides aeration for frequent air bubble- particle collision. Feed: The pipe that is used to supply materials i.e. flotation pulp to the cell. Flotation pulp: A mixture of solids (to be ...

Copper Rougher-Scavenger Flotation Grade-Recovery
Prior to compositing the individual downbank rougher and scavenger cell products, for modal analysis, the metal distribution by flotation cell products was determined. It was apparent from this analysis that most of the lead, presumably as liberated galena in the ore, was recovered in the scavenger circuit.

Pulling more mass has complicated process and mechanical implications as larger mass often cannot be handled by pumps or flotation cells for lack of volumes. For base metals plants/concentrators, a stage process that yields more than 20% mass pull, is likely to fails. It does not concentrate enough.

A practical approach to plant-scale flotation optimization
The only way to reliably know the amount of air entering a flotation cell is to physically measure it with some kind of probe. The APBS can be used to measure J g and bubble size in an industrial flotation cell. It is impractical to physically measure J g each time an air rate is changed on a plant.
