METHOD OF ORE CONCENTRATION Russian patent published in 1997 - IPC

Abstract RU 2095152 C1

FIELD: mineral concentration; ore flotation. SUBSTANCE: pulp is treated with reagents and subjected to flotation to separate foamy product. A part of foamy product is returned to the process along the flotation front. A part of foamy product is returned continuously with amount up to 10-70% of the total yield of foamy product. Time for returning a part of foamy product since the beginning of flotation amounts to 20-70% of the total flotation time. EFFECT: higher efficiency. 2 cl, 3 dwg, 1 tbl
