Particle separation is an important area of interest in many fields, such as the coal and mineral processing industries. A circulating fluidized bed riser system has been built to investigate the separation processes. The system separated the particles into three streams which lead to the dense bin, the product bin, and the filter chamber. Promising results have been obtained which may lead to a system which is viable for commercial separation. The following categories of separation were investigated: separation based on size difference of the particles, separation based on density difference of the particles, and the practicality of separating mineral material, such as pyrite and ash, from coal. The superficial gas velocity in the riser, U 0, and the solids mass flux into the riser, G, were varied in the tests. The separation based on density difference had the most efficient results.
