This paper focusses on the possibility to remove mineral matter (high density particles) from valuable coal fines (-2+1 mm and -1+0.5 mm) by using a fluidized bed operated with and without added vibration, while adding dense media (magnetite, sand and fine coal discards). As a control the bed was also operated without any dense media.
