Abstract

Coal fines are mixed with a magnetite suspension and the mixture is fed to a hydrocyclone. Either or each of the underflow and the overflow, respectively high and low in ash, is subjected to a rougher flotation to recover magnetite as the float fraction. The tailings of the rougher flotation are then cleaned by floating the coal fines.
