depressing effect of flocculants on molybdenite flotation

Apr 01, 2015 · 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, and in the Cu–Mo bulk concentrate

flocculant used used for all kinds of mineral processing

The collector can absorb copper sulphide and make its particles hydrophobic. The copper mines will be recycled through flotation processes. In flotation the air will be passed into the pulp. The foaming agent will also be added to produce bubbles and make the copper
