Beneficiation of Fine Coal Using the Air Table

Processing of thermal coal normally involves the reduction of inerts (mineral matter and moisture) to increase its thermal value. Generally coal is processed using water and even though wet processing of coal is quite efficient it requires an elaborate set up and in many cases is not suitable to operate near the mine site. Wet processing of coal
