Majority of coal preparation plants has been working for over a dozen or several dozens of years. The plant were designed and built neglecting economic criteria. Many buildings and long way of transportation are characteristic for the plants. Many of installed machines and equipment are out of date and done from low quality materials.

· Froth Floatation is the most widely used technique for cleaning coal. It utilizes the difference in the surface characteristics of coal and reuses it to clean ultra fine coal. The mixture of coal and water is conditioned with chemical reagents so that air bubbles will stick on the coal and floats on the top, while the reused particles sink.

liquefaction of coal under pressure range of 18–20 MPa, at the temperatures from 400– 500°C. Because of the absence of alysts, conversion of coal was very low. Commercialization of liquefaction was realized when the first plant in Leuna, Germany was set up in 1927, just after I. G. Farbenindustrie invented hydrogenation alyst in 1826.

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is .

1 Introduction Coal is specified as one of the most important energy resources in the world. Approximately 28% of the energy of the world is provided by coal (BP Statistical Review of World Energy; 2017). Considerable amounts of coal par ticles are accumulated in the tailing dams of washing plants which can lead to serious environmental problems.
