Flotation columns: Getting the most from fine ores - Outotec

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 effective and reliable air spargers for fine

Flotation collectors optimized performance

Phosphate ore is the most important source of phosphorus in fertilizers. To supply the phosphoric acid plant with phosphate, a high grade of phosphorus is essential, as well as reduced levels of impurities such as magnesium, iron and aluminum oxides. Flotation is one of the key beneficiation methods.

Coarse and Fine Particle Flotation Recovery

In The Days of gravity concentration, the art of ore dressing developed on the cardinal principle of saving the values at as coarse a size as possible. Flowsheets were designed which featured an alternation of crushing and concentrating operations.
