TECHNICAL NOTES 9 FLOTATION

Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process In this way a model can be formulated in terms of a rate of flotation which can be quantified in terms of some of the many chemical and physical factors that define the environment inside a flotation cell.

Sparging

Eriez Flotation Division offers a few Sparging options EFD’s patented SlamJet™ air sparging system comprises an air manifold that surrounds the column cell and supplies air to a series of SlamJet™ sparger tub The top of the manifold is fitted with connections for air, as well as connections for a pressure gauge and a pressure transmitter.
