WebA cyclone is a device that uses centrifugal forces to classify solid particles, in a liquid stream, by size and/or density. What does a Cyclone do? If a cyclone is fed with a sand and water mixture containing a range of particle sizes, most of the fine sand will report to the overflow (the top of the cyclone), together with most of the water. WebFeb 20, 2015 · Dense medium separation takes place where particles of differing density fractions are separated via a medium that has a density between that of the two fractions. Particles with a lower density will float, while particles with a higher density will sink.
