Jameson cell Wikipedia

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
