FIELD: mining industry; metallurgy for forming ore mass and tailings. SUBSTANCE: proposed plant includes particle separator for separation of mineral particles by density and/or sizes which is made in form of conveyer belt moved by drive over guide rollers at angle not exceeding 45 deg. to level. Sides of belt which reduce in height in stepwise manner are fixed on frame for separation of layers of material. Reverse side of belt is finned and toothed for reciprocating motion in vertical plane. Height of teeth is no less than half size of maximum particles found in loose mass to be separated. Guide bearing rollers have smooth surface and their diameter exceeds height of teeth by two times. EFFECT: improved quality of separation; simplified construction; low cost. 3 cl, 4 dwg
