Abstract

A method for the use of coal mine residual material containing coal, which comprises passing through a hydrocyclone a slurry in water of crushed waste material having a grain size no greater than 20 mm and of which at least 40 mm. % by weight has a grain size of not more than 1 mm with a grain size distribution of less than 1 snm of: 0.0 - 0.05 mm between 10 and 30%; 0.05 - 0.5 mm between 20 and 50%; 0.5 - 1 mm between 30 and 70%; the density of the suspension being adjusted by addition of water to leave it within the range of 1.22 to 1.45 kg/liter, to separate said residual material into a fraction, rich in coal and a poor fraction in coal.
