The air fraction in the mechanical flotation cell was estimated first. As discussed previously, the estimation considered the effective air flow rate (Q air, m 3 /s), which contributed to the entrainment, equal to the air flow rate entering the flotation cell (Q air,in, m 3 /s) as shown in Eq. (1).

The processing of low grade mineral ores using large scale flotation cells is obviously more advantageous than smaller-scale processing. Large-scale flotation cells have become increasingly important for effective volume scale-up. In this study, the latest and largest flotation cell in China, with an effective volume of 680 m3, is considered. …

Battersby et al. used pneumatic Imhoflot G-Cell flotation cells in which pico bubbles are used to obtain fine nickel and zinc. It is stated that when compared to classic flotation cells, an increase at the rate of 20% in zinc obtaining efficiency and a boost at the rate of 30% nickel obtaining efficiency are achieved.

Imhoflot pneumatic flotation technology has evolved through 25 years of industrial applications. This has led to the development of the patented Imhoflot G-Cell where centrifugal forces are used in the cell to quickly separate the phases after mineral collection and therefore considerably reducing the size of vessels required.

Meanwhile, the mechanical flotation cell mechanism uses an agitator to produce air bubbles. In flotation circuits, mechanical flotation is generally used in rougher circuits because the mineral floatation mechanism is valuable in finding a high recovery, correspond with the function of the rougher circuit. However, mechanical flotation has
