· Flotation in the mining industry is a very significant separation technique. It is known that fine and ultra-fine particles are difficult to float, leading to losses of valuable minerals, mainly due to their low collision efficiency with bubbles. Flotation of fine particles can be enhanced either by increasing the apparent particle size or by decreasing the bubble size.

· The earliest published use of water separation dates to 1905, when German Egyptologist Ludwig Wittmack used it to recover plant remains from ancient adobe brick. The widespread use of flotation in archaeology was the result of a 1968 publication by archaeologist Stuart Struever who used the technique on the recommendations of botanist Hugh Cutler. The …
The present work used the coagulative colloidal gas aphron (CCGA)-involved flotation as a robust technology to efficiently remove the typical engineered nanoparticles - silica nanoparticles (SNPs) from water. The inorganic polymer coagulant - polyaluminum chloride (PACl) was used to surface-functionalize the zwitterionic surfactant (C15B)-based CGAs.

A separation process is provided for treating a feed material comprising silica, feldspar, and metal impurities, including at least one of mica, iron impurities, or refractory heavy minerals, to form one or more products for use in making glass. In the process, the feed material is floated in the presence of a depressant to inhibit the flotation of feldspar and thereby form a concentrate
Circuit for foam separation of diluted thin-dispersion suspension of ash includes performing primary flotation with air flow equaling 0,5-1,5 m 3 /m 2 minutes, and then flotation cleaning of resulting foam concentrate with air flow of 0,1-0,3 m 3 /m 2 minutes and control flotation of chamber product. Resulting concentrate contains 85-98% coal, which may be used in form of …
Haibar's DAF consists of the main tank basin, mixer tank, air dissolving system, dissolved air back flow pipeline, dissolved air water releasing system, skimming device and control panel. The air floatation separation technology is used to achieve a pure water quality. When flocculants (PAC or PAM, or other flocculants) are added into the water, after an effective flocculation process …
Dissolved air flotation (DAF) is based on the separation of the solid-liquid phases with the aid of small air bubbles (10–100 µm), with high values of interfacial contact area, improving the process efficiency. In the process, the air bubbles and particles or flocs form aggregates, which rise to the surface of the flotation cell to be collected. The advantage of producing small bubbles is
In this study, the performance of the cyclojet flotation cell was tested for removing iron-oxides from silica sand ore.
