The application of collectors with nitrile functional groupping for flotation of copper-nickel ores

Abstract

Non-ionic organic Tecflote reagents, having different-structure alkyl radicals and different numbers of functional groups,are investigated as potential flotation collectors for flotation recovery of nickel and copper. The efficiency of their action in respect to recoverable nickel and copper sulfides, is shown by the method of non-frothing flotation of the ore sample treated with chalcopyrite. The application of Tecflote reagents in the ore flotation cycle provided similar indicators for the recovery of valuable metals to those with traditional reagents.
