Flotation: Advantage Circular Cells Mining Technology

Jan 13, 2012· In the near future the BQR2000 (200 m3) and BQR3000 (300 m3) will be available to the market.Kabemba also explained: "Circular cells reduce the amount of dead volume when compared to square cells. This enables a much higher effective pulp volume, hence increasing the effective energy input into the flotation cell.
