Froth Flotation an overview ScienceDirect Topics

The process of froth flotation for upgrading the quality of coal by removing mineral matter (ash and pyrite) has received increased attention since the 1960s. The froth flotation process is typically used for treating <0.5mm size coal and is currently the only technique both effective and economical to clean coal on a commercial scale.
