Separation by gravity. If there is a certain difference in density between two minerals or rock fractions they can be separated by using this difference. Separation by gravity covers two different methods. • Separation in water (Gravity concentration). • Separation in a heavy medium (Dense Media Separation, DMS).

Coal washing involves using water and mechanical techniques and relies on gravity and the difference of density between coal and its' impurities, which are usually more densely packed due to the fact that they are inorganic. Washing coal increases its efficiency and quality, therefore increasing its price.
Coal washing plants in Turkey use gravity separation to beneficiate coal particles larger than 500 μm, and discharge the fine fraction as tailings. In most coal washeries, around 20% of total run-of-mine coal is found to be less than 500 μm.
