Abstract A mathematical model of the dense medium cyclone process has been developed by researchers at the JKMRC over a number of years. It has utilised empirical relationships between key performance criteria (such as cut point and E for the various size fractions) and cyclone geometry and operating parameters. This model is based on an extensive array of data collected from a large number of operating plants as well as pilot plant data. An alternative mechanistically derived model of dense medium cyclone performance based on balancing the terminal velocities of discrete particles due to the centrifugal force experienced in the cyclone against a random turbulent eddy velocity has also been developed from the separation model of Schubert and Neesse. This paper illustrates how the latter model has been integrated into the empirical but more comprehensive JKMRC model in an attempt to provide a more robust model capable of application to a wider range of cyclone operations. In addition, this allows and improved understanding of the key operating characteristics of dense medium cyclones.
