In the case of dry dense medium processes, an air/magnetite or air/sand suspension is utilized rather than water/magnetite, which is commonly used in conventional dense medium cleaning process. The principles of operation of dry coal cleaning are identical to conventional wet processes, except that the difference in specific gravity between air and water have a significant effect
