Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry. The particle size for mineral being recovered is generally less than <0.1mm.

The main functions of flotation separator are to keep particles in suspension, to disperse a sufficient amount of fine air bubbles and to maintain sufficient agitation for bubble-particle attachment before particles are collected in the froth. The Jameson Cell is a high efficiency flotation separator, which uses induced air from atmosphere.

In addition, the high shear used in a conventional flotation cell to suspend the coarse particles and produce air bubbles also acts to break up the weaker particle-bubble bonds, resulting in higher rates of bubble-particle detachment (Jameson, 2012; Kohmuench et al., 2018; Tabosa et al., 2013).
