About the use of R-66 reagent in the technology of flotation enrichment of mixed copper

Abstract

The paper presents laboratory and pilot flotation 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 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.
