Gravity Separation. To effect the gravity separation of coal and mineral matter, 500 g crushed coal (6 mm χ 0) were added to 2000 ml tetrachloroethylene (specific gravity = 1.613) in a large beaker placed in a well ventilated hood. The mixture was stirred by hand to insure wetting of all particles, an d then it was allow ed to stand for 30 min.

2016.6.8 Beneficiation of non-coking coal is gaining ground in India. It not only reduces the volume of inert content to be transported to the power plant and also lowers the wear in the boiler houses. For special applications such as the fuel for integrated gasification combined cycle plant (IGCC), the ash content in the coal should preferably be below 15
