The performance evaluation of dicarboxylic acid monoamides as collectors for copper-nickel ore flotation process

The paper considers review and study of dicarboxylic acid monoamides, which is the nitrogen-containing derivatives class for copper-nickel ore flotation process. The collective properties evaluation of the considered collectors about sulfide minerals is carried out by frothless flotation method and laboratory tests, and the performance of the reagents is compared with traditional collector for copper-nickel ores — xanthate. It has been shown that the trend of specific reagent action in relation to nickel is preserved, and the increase in the proportion of the reagent replacing xanthate grows in nickel recovery.
