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 …
