Column Flotation FLSmidth

When it comes to froth flotation and recovery, there is no one-size-fits-all solution; instead, mining sites find that the best route is to combine multiple pieces of froth recovery equipment, to create a hybrid circuit solution capable of ensuring the best possible recovery rates. Column Flotation Cells are an integral part of that circuit.

Reverse column flotation of iron ore - Mining, Metallurgy ...

May 01, 2007  The use of column flotation was considered for the “reverse flotation” of iron ore, where the gangue (quartz) was recovered in the froth product. This use of the froth for carrying the gangue mineral rather than carrying the valuable concentrate significantly changes the operational requirements of the column. The objective of this work was to determine which of several column flotation ...

What Are Column Flotation Cells?

Feb 06, 2019  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.
