The early attempts at developing numerical methods to determine the optimal design of flotation cells started with the work of Jowett and Ghosh (1965), however their work only considered flotation cells in series. Mehrotra and Kapur (1974) were the first to consider the optimization of the circuit configuration and operation conditions.
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.
