5 mg/L, the average bubbles size decreased substantially Cho and Laskowski2002, studiedthe effectof frothers onthe size of bubbles, in single and multi hole spargers and a flotation cell These authors found that the size of bubbles strongly depends on frother concentration only when multi hole spargers are utilized or when

Jameson cell

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

Flotation Mining: Froth Flotation, Column and Flotation Cell

In the flotation column, air is introduced into the column by means of spray nozzles, causing bubbles which, on a shaft, called a column, which has dimensions larger than the width, cause a countercurrent which will take care of oil and water, to be the activator of the raw material processing process

Up scaling of froth flotation equipment

industrial flotation cell is questioned, while the general trend in flotation cell design of increasing volume even shows an increasing height to diameter ratio, which could eventually lead to a larger fraction of the cell volume being low turbulent
