    The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for

    Froth baffles have also been reported to eliminate dead zones in flotation cells; however, they have not been tested in industrial cells. There are few fundamental studies on physical froth flow modifiers, and most of the information on designing froth flow modifiers and how they impact flotation performance seems proprietary to flotation cell manufacturers
