The role of cationic polyacrylamide in the reverse

The reverse flotation separation of kaolinite and diaspore has been achieved by using the collector dodecylamine (DDA) and depressant cationic polyacrylamide (CPAM) at pH 5.5–8.5. The flotation results have been explained by adsorption measurement, solution chemistry and density functional theory (DFT) calculations.

An overview of the beneficiation of iron ores via reverse

The major advantages of reverse cationic flotation over reverse anionic flotation include the higher flotation rate and superior results in hard water. Ma et al. (2011) have shown that reverse anionic flotation has better results for the flotation of fine particles (< 10 μm) from the Vale iron ore than the cationic flotation of the same material.

The flotation of diaspore, kaolinite, pyrophyllite, illite and the diaspore-kaolinite mixture were studied with a new cationic organosilicon quaternary ammonium collector entitled QAS222. The acting mechanism of the collector with the four minerals was analyzed by Zeta potential measurement and FT-IR spectrum analysis. The results indicate that the QAS222 was effective in the reverse flotation
