As with any engineering project, the systems engineering process for a cell flotation machine is not stationary and may need to be adjusted to respond to changing needs or emerging technologies. The development of a cell flotation machine requires a thorough and iterative systems engineering process.

Standard "Sub-A" Flotation Machines are used for both the rougher and cleaner circuits, where their cell-to-cell principle gives both high recovery and a good grade of concentrate. The rougher concentration is accomplished in 6 or 8-cell flotation machines, with the concentrate from each going to a separate bank for cleaning and re-cleaning.

A high frother concentration produces an excessive amount of froth in the flotation cell. This increases the froth overflow and flotation rate, but, unfortunately it also decreases the concentrate grade. Collector concentration has a significant effect (either linear or non-linear) on all three quantitative response variables.
