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
