INTENSIFYING THE BENEFICIATION OF NORILSK COPPER-NICKEL ORES BY ENERGY EFFECTS

摘要

It is established experimentally that radiation treatment of Cu-Ni ore permits directed change in the granulometric composition of the comminution products with simultaneous increase in the mineral opening coefficient y a factor of 1.5-2 an improvement of the technological beneficiation characteristics. In the Cu-Ni flotation cycle, the extraction of copper an nickel increases by 7.8 an 19.2 percent, respectively, with 1.5-fold reduction in the losses of these metals.
