Flotation columns getting the most from fine ores

The first flotation machine design to use the column concept was developed by Town and Flynn in 1919 – a column was used with an injection of air in the bottom by a porous plate. In subsequent decades, this type of device was substituted by the impeller-type flotation machines in mineral processing plants due to the absence of …

COLUMN FLOTATION MODELLING AND TECHNOLOGY

Because of the efficient cleaning action, flotation columns can upgrade a fine sized concentrate in a single step, where conventional flotation machines would require several sequential stages. Flotation columns offer improved metallurgy, simplified circuits and easier control compared to conventional cells (Coffin and Miszczak, 1982; Wheeler,

SELECTION OF MECHANICAL FLOTATION EQUIPMENT

Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the

What Are Column Flotation Cells?

The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.
