METHOD OF CONCENTRATION OF RAW ORES

摘要

mining industry and other industries. SUBSTANCE: proposed method includes placing the raw ore in liquid medium, subjecting ore to first ultrasonic action in cavitation mode for widening and deepening microcracks. Second ultrasonic action of raw ore is effected at higher frequency as compared with first one. Simultaneously with second ultrasonic action light treatment is effected with the aid of electric lamp of actinic range in the same pipe line. Then, raw ore thus treated is separated into concentrated components on separator. EFFECT: enhanced efficiency of development and obtaining valid components, heavy fractions in particular. 4 cl, 1 dwg
