Dense Medium Cyclone Handbook - ACARP


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:

A cyclone is the heart of the washing unit in a Heavy Media Washery. It is a non moving part and hence requires very low maintenance. However, the pressure at the inlet of the cyclone is a very important factor and it is suggested to maintain a minimum pressure of around D x 9 x 9.81 x density/100 (in bars), where D = the inner diameter of the ...
