Washing medium is a mixture of sand and water. A deep bath of sand and water having intermediate. specific gravity between clean coal and ash is. used. Clean coal floats and dirt sinks and removed. 8. Tromp Process. A shallow bath instead of deep bath of sand and. water is used.
Flotation tailings are by-products of coal preparation plants, which do not only occupy cultivated land but also cause pollution. The high ash content and low calorific value of tailings limit their applications. Deashing is the precondition for the reutilization of flotation tailings. However, it is more difficult to remove ash content from flotation tailings …

From the graph shown in figure 8, it can be inferred that the benefits of coal washing, up to 34% ash in output coal, offsets the cost of washing at distance of 600 and 700 km for G13 and G12 grade and around 1500 km for G-11. The difference observed in washing upto 34% and 32% is the distance for G11.
