METHOD OF CONCENTRATION OF ORES Russian patent published in 1998 - IPC

Abstract RU 2111063 C1

FIELD: concentration of mineral resources, applicable in flotation of ores. SUBSTANCE: in the initial stage of flotation, which may last within 50 to 40% of the total time of flotation, ore is separated into froth and chamber products, after which the whole froth product is returned back to the zone of aeration. In this case mineral particles of the returned froth product are beyond competition, on the contrary, they serve as a catalyst both in the elementary act of flotation and in extraction of floated particles on the whole. An essential acceleration of flotation of waterproofed particles is going on, efficiency of use of conveyed air bubbles is enhanced, which results in a more considerable increase of the difference in the rates of flotation of useful and depressible (contaminating) minerals. EFFECT: enhanced efficiency. 3 tbl
