The flotation of gold bearing ores — A review
The control of aeration, agitation speed and pulp density in the flotation cells has also been shown to be crucial in the flotation of gold. The upper size of gold recovered efficiently under turbulent conditions has been reported to be as high as 0.71mm at > 80% recovery [67].

Notably in Fig. 5, kaolinite recovery exceeded 25% at a water recovery of 32% in the mechanical flotation cell, while in the RFC, kaolinite recovery was approximately 5% at 13% water recovery. It is quite apparent that kaolinite entrainment was markedly higher in the mechanical flotation cell compared to the RFC.
