Coal dense medium separation dynamic and steady-state

Coal dense medium separation is a popular beneficiation process used for the upgrading of coal ore into power station and metallurgical coal. The control systems used in coal beneficiation are often limited to localised regulatory control of feed rate and medium density. A coal dense medium separation process can benefit substantially from

Dynamic model for a dense medium drum separator in coal

Figure 1: Dense medium drum circuit (Adapted from England et al. (2002)). Drum separators operate on the principle of float and sink separation where particles of di erent densities to the medium can either float or sink in the medium due to gravity. Coal feed is mixed with the medium and processed through a relatively static container.
