It is a new type of device that overcomes the design and operating inadequacies of column and conventional mechanical flotation cells [147]. The Jameson cell was first tested and commercially installed at Newlands Coal Pty Ltd. [148]. The feed was cyclone overflow particles with size of minus 20–25 μm and ash content of 15–50%, which were previously discarded

Since Jameson Cell flotation technology was first installed in a coal flotation application in 1988/89 at Newlands Coal Handling and Preparation Plant (CHPP) there have been fundamental improvements to its design which has led to its current status as the leading technology in Australia for fine coal flotation. These improvements, which include key hardware modifications, consist of the re

A form of column flotation cell is described in which the contact between the feed and the air stream is made in a mixing device at the top of a vertical downcomer. The air-liquid mixture flows downward to discharge into a shallow pool of pulp in the bottom of a short cylindrical column. The bubbles disengage and rise to the top of the column to overflow into a concentrate launder, while the

Jameson flotation cell produces finer than one mm air bubbles due to its working principle. The fine bubbles cause the increase in possibility of collision, and therefore the Jameson cell is appropriate for flotation of fine size liberated ores. Furthermore, flotation in the Jameson cell is shorter than in the conventional flotation devices and
