Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper 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; DIFFERENTIAL SEDIMENTATION (sedimentation …

Flotation Froth flotation (or simply flotation) is a physico-chemical separation process that utilises the effect that different materials normally show also differences in surface properties (e.g. surface tension), for separating a mixture of materials into its fractions. This difference in surface properties yields in a different tendency of

Influence of Froth Height on Column Flotation ...

The influence of the froth height in the reverse flotation of kaolinitic ore was analyzed based on the recovery by entrainment and by true flotation of iron, titanium and manganese oxides (FeO, TiO2 and MnO). Also, the influence of the particle size in the drainage process was analyzed. The recovery by entrainment and by true flotation of the three oxides is inversely proportional to the froth ...

Outotec - FrothSense sensor system for flotation process ...

Traditionally, flotation plant operators have had to depend on visual assessments of froth appearance when making operative decisions. The FrothSense system measures several essential properties of froth appearance, including froth speed, direction, bubble size, froth stability and froth color, while also providing statistical data related to these variables.

Tin values in the form of cassiterite (SnO.sub.2) are recovered from aqueous pulps of finely divided cassiterite-bearing ore, preconcentrate or concentrate by froth flotation. The ore pulps are deslimed thoroughly, partially or not at all. Slimes, gangue or waste minerals in the pulps are selectively depressed by use of a metal salt/silicate reagent combination.

Flottazione - Wikipedia

La froth flotation viene impiegata per la separazione dei minerali dalle loro ganghe, sfruttando la loro differenza di idrofobicità.. Al fine di aumentare ulteriormente la differenza di idrofobicità da minerale e ganghe, si utilizzano dei tensioattivi.. Tra i minerali che vengono trattati con questa metodologia si annoverano: solfuri, ossidi, carbonati e fosfati, e anche oro metallico.
