Molybdenite flotation from copper/molybdenum concentrates

Typically, rougher molybdenite flotation and recovery from bulk copper/molybdenum concentrates involves the use of alkalisulfides, Nokes reagents, cyanides, oxidants, and/or thermal treatment to depress copper sulfide minerals. The bulk copper/molybdenum feed generally varies from 0.2% Mo to 1.0% Mo, and with traditional reagents the single-stage rougher flotation recovery of molybdenite

Sequential Copper–Lead–Zinc Flotation

To improve the selectivity between copper and lead, a sequential copper-lead-zinc rougher circuit was tested. Each of the rougher circuits had a dedi ed regrind and cleaner circuit. The advantages of the sequential circuits are that the levels of selectivity can be increased, particularly for copper and lead. With this process, copper was recovered first with MBS depression of lead, zinc and

Model Predictive Control for Froth Flotation Plants

Froth flotation Froth flotation is a common method to extract a certain type of mineral from ore while depressing the amount of undesired minerals in the extracted concentrate. It is done by adding certain chemical reagents to selectively rendering the desired mineral hydrophobic. In a flotation cell, air bubbles then lifts the mineral.

Separating Minerals by Floatation

Copper Floatation Process Appli ion The process starts with crushed ore. A ball mill receives the crushed ore and reduces its particle size to the consistency of sand. Next, the ground ore from the mill often travels as a high-solid slurry to a cyclone. The cyclone separates fine particles from heavier particles, which return to the ball mill for further grinding. The cyclone overflow
