Column Flotation Cells

Selected topics in the rapidly evolving field of column flotation are reviewed. The status of column scale-up concerns is assessed, with particular emphasis on recent measurements of froth zone performance. Column circuits are reviewed, and some performance comparisons between column and column/mechanical cell cleaning circuits are made.

froth flotation cells The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles.

Column flotation cells are used in roughing and cleaning duties on a number of mines treating gold ores (Lane and Dunne, 1987). A column cell typically provides higher concentrate grades compared to a mechanically agitated cell; however, losses of coarse gold may be higher in the column cell (Chryssoulis et al., 2003b).

Hydrophilic particles flow down and leave the column through a barometric leg, which includes a level control system. This corresponds to the underflow and, in the case of direct flotation, to the tailings. Figure 2 illustrates the flotation process within a column. Figure 2. Flotation process within a column.

COLUMN FLOTATION. ABSTRACT. Industrial application of column flotation began in earnest in the early 1980’s, and is now accepted as a conventional application. For example, most of the world’s major copper producers use column flotation as the final stage of cleaning.

The ability to use wash water to remove entrainment revived the interest in flotation columns. L/D ratio is also significant for ultrafine particles. The coal industry is shifting to larger columns, up to 4.5m diameter and greater.

each cell requires additional energy. Column cells are also mixed tanks due to the flow characteristics of the air and feed slurry. Several investigations have examined the mixing characteristics of laboratory and industrial column flotation cells in mineral applications (Dobby and Finch, 1990, Yianatos et al, 2008).

Description. From a continuous column flotation machine with a 7 cm diameter laboratory column flotation cell, to Denver type continuous flotation machines, with usable volumes from 7 liters to 1.4 Cubic Meters, we have a complete selection of pilot scale flotation machines.

column cells to provide impressive levels of metallurgical performance closely approaching the ultimate separation curve predicted using flotation release analysis. Another very important feature of column cells is the gas sparging system. Unfortunately, field studies suggest that gas injector systems are not always optimized.

Currently, Australia ranks third in terms of installed column flotation area behind China and Canada (Figure 1). Almost 15 per cent of the world’s flotation column capacity ...

Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles.

Flotation column cells are flotation act as three phase settlers where particles move downwards in a hindered settling environment counter-current to a flux of rising air bubbles that are generated by spargers located near the bottom of the cell.

Column Flotation. Flotation columns work on the same basic principle as mechanical flotation cells – mineral separation takes place in an agitated and/or aerated water mineral slurry where the surfaces of selected minerals are made hydrophobic (water-repellent) by conditioning with selective flotation reagents.

sequential stages. Flotation columns offer improved metallurgy, simplified circuits and easier control compared to conventional cells (Coffin and Miszczak, 1982; Wheeler, 1985; Feeley et al., 1987). Development and industrial applications of flotation columns have been described in a large number of references.
