METHOD OF EXTRACTION OF SMALL GRAINS OF USEFUL COMPONENT AT MINING OF CLAY PLACERS AND NODULAR OXIDIZED ORES OF WEATHERING CRUSTS Russian patent published in 2003 - IPC

Abstract RU 2214867 C1

FIELD: preparation of metal-bearing sands for concentration by gravitational methods; mining of minerals of placer deposits and weathering crusts. SUBSTANCE: proposed method includes washing, disintegration, delivery of pulp to deep filling sluice, gravitational concentration in deep filling sluices, screening, gravitational concentration in shallow sluices, rinsing of concentrate from entrapping surfaces of deep and shallow filling and bringing to planished metal state; before delivery of pulp to deep filling sluice, it is subjected to electric blast treatment and activation in buddle bin. EFFECT: enhanced efficiency. 3 cl, 2 ex
