#### 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. This number needs to bemass balance in flotation plant Solution for ore mining,During discussion of the mass balance of SiO2 at the Bowater plant in calcium soap collector chemistry was inferred from the flotation cell mass balance flotation mass balance formula OneMine Mining and Minerals TITLE: Roasting Of Refractory Gold Ore And Concentrates : SUMMARY 7.
