Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral /water slurry (Klimpel, 1995). The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain ...

Figure 1: The flotation system includes many interrelated components, and changes in one area will produce compensating effects in other areas (Klimpel, 1995) Froth flotation is a good example of an engineering "system", in that the various important parameters are highly inter-related, as shown in Figure 1.

Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water). Since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold.

Flotation A Denver flotation cell was used at a rotor speed maintained at 1200 r/min for all batch flotation tests. The collector, sodium isobutyl xanthate (SIBX), was maintained at 300 g/t for all batch tests while frother (SAS FROTH) and depressant (DLM), which is a mixture of natural and modified polysaccharides) dosages were varied.

The froth flotation process mainly includes grinding, slurry adding, froth flotation separation and dehydration of products and tailing products after froth flotation. Before the flotation operation, the ore needs to be ground to an optional size range by the grinding mill, generally less than 0.1 mm.

In the attempt to process lower-grade ores, mineral flotation has taken centre stage as the preferred recovery route. However, in many instances, the froth product does not have a high grade due to the entrainment of gangue minerals. Industry has solved this challenge by introducing froth washing mechanisms. Clean wash water is introduced into or on top of the …
