The invention relates to a total-,tailings paste filling, and stockpiling combined treatment method based on a deep-cone thickener. A combined treatment system is composed of a one-stage or multi-stage ,pump, station, the deep-cone thickener and a two-segment horizontal stirring device. The deep-cone thickener is arranged near the multi-stage ,pump, station.

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.
