The paper presents the results of technological studies on poor and rebellious nickel and phosphorus mineral raw materials. The authors have found that optimized regime of rebellious finely disseminated copper–nickel processing with reagents–dispersers allows increasing recovery of nonferrous metals into concentrate and decreasing their content in flotation tailings. The authors propose new complexing collectors with hydroxamate and hydrazide groupings and, on their basis, the reagent regimes for flotation of sulphide nonferrous ore. The potential application of these reagents instead of Aeroflot with improvement of technological parameters has been shown. The authors have defined high efficiency of the reagents based on polyalkyl benzene sulfonates and hydroxamic acids in reverse flotation of nepheline from apatite–nepheline ore with a high content of titanium-bearing minerals. The specific action of these reagents and the strength of the dark-colored mineral attachment ensure high selectivity of separation. The paper demonstrates high efficiency of anionic polyacrylamide flocculant in water treatment technologies at apatite–nepheline dressing plants.
