Jun 30, 2005 A mathematical model is proposed to describe the multiphase flow in a dense-medium cyclone (DMC). In this model, the volume of fluid multiphase model is first used to determine the shape and position of the air core, and then the mixture multiphase model is employed to describe the flow of the dense medium (comprising finely ground magnetite in water) and the air core, where the

Jan 15, 2018 The dense medium separation process (DMS) is a mature technology, and is widely used in mineral and coal processing. The dense medium cyclone (DMC) is the most ubiquitous of the DMS vessels in use, and deservedly so. It is efficient (when run properly), can process both coarse and fine sizes, and has a relatively small footprint.

Pretoria in 1976. The plant was equipped with a single 150 mm diameter dense-medium cyclone supported by all the additional equipment needed to feed the cyclone and recover magnetite. The cyclone was fed at feed pressures ranging typically between 80 and 150 kPa (40 to 70D). The plant was employed to test the beneficiation of fine coal

Dense medium cyclones were introduced into Australian washeries in the 1950s. Modern circuits continue to be based on the strong foundations provided by the Dutch State Mines and Stamicarbon BV, but over the ensuing decades, many innovations have been trialed. Many have been rejected and others have proven useful and have been widely adopted:
