The paper presents laboratory and pilot flotation click here tests of the R-66 reagent on samples of mixed copper ore from the Konyrat deposit.The medium regulator reagent was supplied to the main flotation.Laboratory tests of the technology of flotation concentration on ore with a copper content of 0,31 % in a closed cycle in the optimal mode: R-66 - 100 g/t, sodium sulfide - 150 g/t, xanthate - 45 g/t, blowing agent - 60 g/t allows to vegas golden knights background extract copper into concentrate up to 85 %.At the same time, the copper content in the concentrate after two cleanings was reached at the level of 4,5 %, sulfur 42,3 %.At the same time, the R-66 reagent (100 g/t) makes it possible to completely eliminate the use of lime (1 000 g/t) in the ore dressing scheme.
