JAMESON CELL

About Jameson Cell. The Jameson Cell technology was invented in the late 1980s to overcome the design and operating inadequacies of column and conventional cells. From its ˜rst commercial installation in 1989 it has been continuously improved to make it more robust and easy to use. The latest, Mark IV Jameson Cell, combines the original

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

Influences of Jameson flotation operation variables on the

Apr 24, 2009· Pulp densities used in flotation columns are generally lower than those used in mechanical flotation cells. It is well known that pulp density is an important parameter, so column flotation experiments were carried out at different pulp densities (7.5–20%) in the Jameson flotation cell in order to determine its effect on the recovery of UC.

The kinetics of Fast Flotation using the Reflux Flotation Cell

Mar 16, 2019· 1. Introduction. The first-order kinetic model is commonly used to describe the flotation process (Ahmed and Jameson, 1985, Sutherland, 1948).For a given recovery, higher flotation kinetic rate constants lead to the need for a shorter residence time of the slurry in the flotation cell, thus offering the potential for reducing the volume capacity of the flotation cell.
