Get PriceDensification and Dense Medium Control Strategies The control of the medium density is a major factor in the operation of the dense medium separation process. The medium density must be kept in close tolerance to the target or setpoint density to avoid displacement of near density material which will affect the yields and product grades.
Get PriceDense 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:

Get PriceFrom the early 1960’s until the mid 1980’s, dense medium cyclone circuitry design technology did not change appreciably. The basic design, which was both highly flexible and highly efficient, was consistent with technology developed by the Dutch State Mines (“DSM”) in the mid 1940’s. During this period, the “typical” dense medium cyclone circuit was designed to process raw coal ...
