How To Increase Molybdenum Grade In A Flotation Plant

The most interesting part of the flotation curves is the increase in recovery of molybdenum with ultrasonic power, as shown in Figure 35.29. The increase in recovery of iron is not good news for copper mines because the more iron floating the lower grade of recovery. This may be because the iron becomes more hydrophobic with ultrasonic action.A process mineralogy approach to optimize molybdenite,Oct 01, 2020· As shown in Table 1, molybdenum content in the feed and final concentrate of the molybdenum plant is 0.47% and 48.70%, respectively, and copper content in the final molybdenum concentrate was 1.46%.

The Importance of %Mass Pull in a Flotation Circuit What

What is flotation mass pull and why does it matter so much? If we consider the total Plant Feed of 2800 TPD as 100% of the mass and we produce say 59% Cu Recovery or 84 TPD of Cu conc, we would find that 3% of the “mass” is in the concentrate. We therefore label %Mass Pull as the % of the material (mass) sent to flotation a “pulled/floated” into the concentrate.
