Froth Flotation Perlite

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Flotation Reagents - Mineral Processing & Metallurgy

Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

Flotation of coarse coal particles in a fluidized bed: …

The fluidized bed froth flotation device consists of a vertical column, with an upflow of water that is introduced into the base, sufficient to fluidize the coarser size fraction in the feed, see Fig. 2.The principles have previously been briefly described in Jameson, 2010a, Jameson, 2010b.The coarse particles settle in the bottom, and fine particles are elutriated out of the bed.

Optimum Froth Bed Depth Levels

When the pulp levels on all cells appears high (shallow froth bed thicknesses or depth). This causes unstable froth which constantly produces a low density “run-away” or wet, watery un-drained rougher concentrate rich in mechanically floated (entrained) “other materials” and containing most of the frother (added to flotation feed) itself. ** Operating at shallow froth bed causes much ...
