Jameson cell


The Jameson Cell grew out of a longterm research program aimed at improving the recovery of fine particles by flotation. The work started at Imperial College London, and continued when Jameson moved in 1978 to the University of Newcastle, NSW, Australia, where he is Laureate Professor (2015).
Jameson's research into flotation began when he was at Imperial College London, in 1969. A colleague, Dr J A Kitchener of the Royal School of Mines, pointed out that many of the new mineral deposits bein

Column and Contact Cell Flotation Mining SGS

The uncollected particles are removed through an underflow line. As with a flotation column, the froth may be water washed meaning the contact cell can also be used as a cleaner cell. The contact cell is mainly used in rougher flotation circuits. It is compact, highly efficient, simple to operate, and has low energy and maintenance costs.

AMIT 145 Lesson 5 Froth Flotation Mining Mill Operator

Flotation Circuits. Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks. Rougher and scavenger banks are focused on recovery and thus provide maximum residence time. Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses.

Flotation optimization. Lost recovery in the flotation process results in lost revenue. Mines now need to process more complex ores making the operation of flotation circuits more difficult. Our service helps identify the optimum feed size, cell design and operational parameters to maximize recovery and

Flotation columns Getting the most from fine ores Outotec

In direct flotation, columns have been used mainly for cleaner stages due to their capacity for generating highgrade froths with fine material. The most common configuration involves a rougher with mechanical cells and a cleaner with columns, after regrinding the intermediate concentrates. This type of flowsheet aims at minimizing grinding costs.

Froth flotation


Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution) so that the various minerals exist as physically separate grains. This process is known as liberation. The particle sizes are typically less than 0.1 mm (100 181;m), but sometimes sizes smaller than 710 181;m are required. There is a tendency for the liberation size of the minerals to decrease over time as the ore bodies with coarse mineral grains that can be separated at larger sizes a

The process is also different in the new plant, consisting of four consecutive cleaner banks. In the literature study, it was found that a flotation cell has many sub processes which are connected from the mixing zone in the bottom to the top of the froth. These sub processes have an effect on each other and it makes the flotation a complex

Flotation stabilization and optimization SAIMM

Levels in flotation cells are conventionally controlled by PI (proportional and integral) control loops. PI control will work well when the cell being controlled is isolated. However, flotation cells are connected in a network and the tailings stream from one cell is likely to be fed to another cell.
