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.

Influence of Ferric and Ferrous Iron on Chemical and ...

The effects of ferrous and ferric iron as well as redox potential on copper and iron extraction from the copper flotation concentrate of Sarcheshmeh, Kerman, Iran, were evaluated using shake flask leaching examinations. Experiments were carried out in the presence and absence of a mixed culture of moderately thermophile microorganisms at 50C.

Effect of pH on Copper Flotation Recovery VS Mass Pull

An example of testing the effect of pH on rougher flotation on pit samples and the results are presented. Since this is only an example, it needs reminding that not all ores will respond the same. Here, rougher flotation is most Selective at a pH of 9.5 as pH levels in the 9 to 10 range yielded 1% to 2% better recoveries. Mineralogy data also supports this and shows between 3% and 10% of the ...

Effect of iron content in sphalerite on flotation ...

The effect of iron, substituted in the mineral lattice, on the froth flotation of sphalerite has been investigated at alkaline pH. It has been found that a critical copper sulphate concentration exists where sphalerite recovery is maximized, above which the recovery of sphalerite then decreases.
