Guide to Flotation Cells in Mineral Processing
The flotation process and related flotation cells are widely used for treating metallic and nonmetallic ores and in addition, it is receiving an ever widening application in other industries. A greater tonnage of ore is treated by flotation than by any other single process. Practically all the metallic minerals are being recovered by the flotation process and the range …

Flotation behaviour in reflux flotation cell – A critical review
The change of flotation feed size leads to new challenges in designing flotation equipment and circuits. For conventional flotation circuits, a typical feed size is in the range of 75–150 μm (Jameson, 2010b).As described in the famous 'elephant curves', for most of the base metal sulphide minerals, this size range provides the highest recovery in conventional flotation …
