Cemented rock fill (CRF) 12. High-density or paste fill Mill tailings including slimes, sand, waste rock or gravel from 0 to 25 mm are dewatered down to 12-15% of water content, classified and concentrated by elimination of light particles. In resulting mixture the volume of fine material must exceed the pore-volume of the coarse fraction.
