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.

Pyrite is removed from coal by a 2-stage froth flotation. In the 1st stage, coarse pyrite is removed as underflow in a conventional froth flotation operation. In the 2nd stage, the froth product from the 1st stage is subjected to froth flotation by using a coal flotation depressant and a pyrite flotation collector, thus removing most of the fine pyrite.

The Application of Xanthate in Froth Flotation Process ...

Pyrite can use xanthate as the collector in acidic, neutral and weak alkali slurries. The acid-treated pyrite has good floatability (the optimum pH for the use of xanthate is 4.5). For the flotation of pyrite, the ability of xanthate to collect is better than that of dithiophosphate. 2. Xanthate Application in Sphalerite Froth Flotation

The second tin concentrate from flotation at about pH 5 is then mixed with the magnetic concentrate from the magnetic separation step and conditioned with glue. Flotation is carried out at between about pH 4.5 and 5.5, preferably about pH 5.

Sulfur reduction in Sangan iron ore by flotation

than the norm of iron ore. Pyrite is the main source of sulfur in this ore which is accompanied with less amount pyrrhotite. So in order to reduce the sulfur content, reverse flotation was designed in concentration plant. Thiol collectors are commonly used in the froth flotation of sulfide minerals. The xanthates,

pyrite during the cleaning operation. The flotation pH in most of the plants is above 10 and most often over 11. The relatively high pH used in the operating plants is not designed to depress pyrite, but rather as a frother modifier. In reality, the higher pH produces a stable froth with better carrying power than at a lower pH for the majority
