    Coal has traditionally been treated by gravity separation techniques, most suited to the cleaning of coarse coal (particles with diameter greater than 1.0 mm. Fine coal was generally discarded (Mohns, 1997). In 1950 M.King Hubbert calculated feature oil production rate. We all known as ‘Hubbert peak1 Same as this calculation in recent years has been a significant decreases in coal reserves. Especially higher grade coal deposits. The fine coal recovery has resulted recovery of tailings from traditional coarse coal cleaning process. Because of fine coal content in mineable coal is 35%, and for some reaches 60%.
