Depressing effect of flocculants on molybdenite flotation

In this work ?otation tests demonstrate that conventional ?occulants, high-molecular weight anionic polyacrylamides (PAM), are strong molybdenite depressants. Low-molecularweight shear degraded polyacrylamides in spite of losing ?occulation ef?ciency maintain depressingability for molybdenite.

Depressing effect of flocculants on molybdenite flotation.

Processing of Cu-Mo ores includes two steps: a bulk flotation where molybdenite is recovered together with Cu sulfides, and a subsequent selective flotation step where molybdenite is separated from depressed copper sulfides. Flocculants are usually employed in the middling thickeners in the copper plant,...

Review of the flotation of molybdenite. Part I: Surface

Effect of O-CMC on selective depression of molybdenite: (a) single-mineral flotation in 1 mM KCl solution with 20 ppm KIBX at pH 9 under various concentrations of O-CMC; (b) flotation of artificially mixed minerals (chalycopyrite:molybdenite = 1:1 by weight) in 1 mM KCl solution with 20 ppm KIBX and150 ppm O-CMC as function of pH, and atomic
