The chemistry design requirements for floating coarse particles have been known for a long time, but the physics of traditional flotation cells - primarily froth zone dynamics - presented a constraint in the implementation of these reagents. Over the past two decades, flotation cell manufacturers have overcome those physics limitations and have ...

The Australian coal industry quickly adopted the new technology and Jameson Cells have been the main method of flotation used to separate coal during the last stage in the coal wash for the past 20 years. "The very, very fine material that can't be recovered through a gravity or screening system is recovered by flotation," said Lawson.
