Froth flotation of gold is a widely used beneficiation method for treating rock gold ore in gold concentrating plant, which is often used to treat gold ore containing sulfide minerals with high floatability. The froth flotation process can concentrate the gold in sulfide minerals to the maximum extent, and the tailings can be directly discarded.

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.

Fine particles have a relatively high surface area, and therefore more reagents are needed for their processing. In addition, the problem of fine particle flotation is mainly due to their low collision and attachment efficiencies with bubbles. Several strategies are proposed in the literature to overcome the problems of fine particle flotation.

At the Wiluna mine, the gold ore was floated at a slightly elevated pH of 8.2 using copper sulfate, PAX, and Interfroth 50. A unit flotation cell was included in the milling circuit at the Beaconsfield mine. Copper sulfate was added to the mill, while SIBX was distributed to three different locations in the flotation circuit.

His design adapts the eponymous Jameson Cell he patented in the late 1980s. In contrast to the HydroFloat, his cell treats fine and coarse together. The flotation feed cycles past an airjet first, where it encounters the high energy useful for attaching fine particles to bubbles. "That's like the Jameson Cell, actually," he said.
