Abstract
The laboratory continuous air dense medium fluidised bed separator was tested on the high ash coal of Genesee Mine and has proven to be an effective method for coal dry cleaning. The results show that we can get a yield of 80% with an ash content of 10%, which is a good achievement from the feed coal that generally has an ash content of 26%. The effect of air velocity, bed height, and time of fluidisation and comparison of different media were studied. The design of the continuous batch mode apparatus requires modification, so that better flow at the bottom end can be achieved. This will allow the higher specific gravity coal particles to move towards the discharge side.
