Dense Medium Separators- Wemco Cone Feed ore and dense medium are introduced into the vessel. The sinks are removed by a bucket elevator system and the floats overflow from the top of the vessel. The Wemco has a high sinks capacity and is commonly used for ore treatment. The cone has a diameter ≤ 6m and can treat particle sizes ≤100mm at a throughput ≤500tph.

Some coal dense medium separation plants typically include a DMD separator. The operational management of this unit process is often limited to localised control of medium density and feed mass flow rate. Dynamic models for coal dense medium separation have been developed by the authors with the intention of using them for dynamic control.
