For the necessary direct fine grinding of the run-of-mine lignite coal, RWE has developed a special process with two grinding stages connected in series for the reduction of the grain size of the raw lignite coal from around less than 80 mm to the desired value of less than 2 mm. Fig 3b shows the overall process of fine-grain WTA process ...

Beneficiation is the process whereby the extracted material is reduced to particles which can be separated into mineral and waste, the former suitable for further processing or direct use. The operations that take place in beneficiation are primarily mechanical, such as grinding, washing, magnetic separation, centrifugal separation, and so on.
