The copper flotation circuit consisted of four OK 3 rougher and scavenger cells. Rougher concentrates went through two cleaning stages in OK 1.5 flotation cells. Flotation tailings were thickened to 60% solids on a third supaflo thickener before disposal. Thickener overflow diluted feed to talc flotation cells. 1.6 Carbon Transfer

In order for flotation cells to perform effectively, these requirements have to be met and thus optimal use of energy is critical to the process. The distribution of the energy dissipation rate within a flotation cell determines both the capture of ultrafine particles (high shear) and the detachment of coarse particles (low shear) (Jameson, 2013).
