The coal is dried in a fluidized bed dryer and fine coal is separated, and then agglomerated by an agglomerater. Next, the agglomerated fine coal is added to the coarse coal, and charged into coke ovens. The coal is pre-heated rapidly to 350 C in a pneumatic pre-heater, and carbonized in the coke oven.

In dense media separation a media is created with a density in between the density of the ore and gangue particles. When subjected to this media particles either float or sink depending on their density relative to the media. In this way the separation takes place purely on density differences and does not, in principle, relay on any other factors such as particle weight or
