  • 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.
