Process for the separation of rock refuse and coal ...

A process for separating a coal containing rock material into a first rock fraction that is rich in coal and into a second rock fraction that is poor in coal, which comprises mixing a starting material consisting essentially of coal-containing rock that contains not more than 50% by weight coal, said starting material having a maximum particle size of 50 mm, and at least 7% by weight of said starting material comprises rock particles having a maximum particle size of 0.5 mm, with a suspension having a preadjusted density, the solids content of said suspension originating entirely from the starting material, introducing the resulting mixture into a hydrocyclone, passing the material obtained from the hydrocyclone through a sieve while separating coal rich and coal
