TECHNOLOGY OF COMPLEX PROCESSING OF PRIMARY FLOCCULENT MASS Russian patent published in 2002 - IPC

FIELD: recovery of mineral resources, peat, sapropel, processing of rock construction materials, man-made formations and storm run-off. SUBSTANCE: technology of complex processing of primary flocculent mass includes screening of starting material into fractions of different size and their subsequent separation with the aid of concentrate- processing complex. This complex carries out gravity separation to produce rough concentrate and light fraction, reprocessing of rough concentrate and light fraction with winning of finished concentrates with various physical properties and tailings. After screening products of large-and medium-sized fractions left on screen and product of largest fraction from under screen are crushed to size of smallest fraction and crushed fractions are combined. Product of medium fraction from under screen together with product of small fraction above screen and crushed fraction are separated in concentrate- processing complex. At least one finished mineral and/or single-mineral concentrate is won in addition at stage of gravity separation. New single-mineral and/or mineral concentrates with another physical properties are won at stage of re- separation. Re-separation tailings are returned for beneficiation into complex or pressed. Product of small fraction from under screen is separated with the use of sluicing box at least one flight of which has wavy bottom of variable curvature in longitudinal section. At least one concentrate and tailings intended for pressing are prepared. EFFECT: invention reduces loss of valuable mineral resources and diminishes dimensions of dumps. 15 cl, 1 dwg
