A compartment model for the mass transfer inside a conventional
A model is developed by taking into account the simultaneous mechanisms of true flotation and entrainment in a conventional flotation cell. The total volume of the cell is divided into three compartments: pulp collection zone, pulp quiescent zone and froth region, with the mechanisms being modeled as occurring at the same time but originating at different places: …

A scale-up approach for industrial flotation cells based on …
The flotation scale-up depends on the standard batch procedures, the industrial cell sizes and designs, circuit arrangements, number of cells, as well as plant operating conditions. Experimental evidence has shown that the apparent flotation rates at which the valuable minerals recover in industrial plants are lower than that in laboratory test.

The E-MPC strategy proposed in this study considers a rougher froth flotation cell. The rougher cell objective is to recover as much valuable metal as possible while maintaining the desired concentrate grade. The concentrate is sent to further stages, usually to cleaning cells, where the objective is to increase the concentrate grade.
