METHOD FOR EXTRACTING SMALL GRAINS OF USEFUL COMPONENT IN MINING CLAY PLACERS Russian patent published in 2003 - IPC

Abstract RU 2209677 C1

FIELD: preparing of metal-bearing sands for concentration process. SUBSTANCE: method involves washing and disintegration of sand on perforated table of hydraulic buddle with the use of hydraulic monitor jet having elliptical section, with long axis of jet section being arranged in parallel with perforated surface during washing procedure; providing gravitational concentration in deep and shallow sluices; rinsing concentrate from deep and shallow sluice catching surfaces in head and tail parts; developing to placer metal. EFFECT: increased efficiency in extracting small grains and increased capacity of hydraulic buddle. 2 cl, 2 ex
