Working out of a garage and with their own money, they began building a machine that optimized the phases of particle collection, bubble separation and froth recovery. The result was the SFR, a flotation cell that reduces operating costs, power consumption, and floor space by up to 50 per cent, and cuts air consumption even more.

A combination of laboratory-scale test work and design scale-up factors will determine residence time. However, the froth carry rate (dry tonnes of concentrate per square metre of froth surface area per hour, t/m2/hr) and froth lip loading (dry tonnes of concentrate per metre of froth lip per hour, t/m/hr) cannot be determined in a laboratory.
