What is flotation mass pull and why does it matter so much? If we consider the total Plant Feed of 2800 TPD as 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.
