The art and science of dense medium selection
Medium suspensions play an integral part in the successful application of dense medium separation for both static and dynamic separators. Although models exist to predict particle movement as a function of medium density and viscosity, these models have been derived on the assumption of Newtonian rheology.

Dense Medium Separation
The deep bath type dense medium separators of the early 1920's to 1940's, which used scraper chains for product removal, have been replaced by drum and wheel designs from the 1950's to present. Coarse feed bath separators currently used in the minerals processing industry are predominantly of the

Dense medium separators (DMS) separate particles based on their density and can process coarse particles ranging from 0.5 mm to 50-70 mm, usually in the 1- 50 mm range. The Condor separator can separate particles into either two (concentrate and tailings) or three products (concentrate, middlings, and tailings).

Dense medium separation | Machines
The typical dense medium drum is quite short (only 1.0 – 1.5m in length), and it happens quite often that before a particle can float or sink, it is already out of the bath. Therefore, in the Ad Rem design the length of the separation zone is greatly extended, increasing the residence time of a particle in the bath, therefore making it ...
