Abstract
Test data on the selective reagent modes at bulk flotation cycle and modified carboxymethylcellulose (CMC) at a selection cycle for the bulk copper-molybdenum concentrate. The selected reagent mode at a bulk flotation cycle with industrial kerosene and Beraflot as collectors and OPSB as a frother made it possible to recover 87 % of copper and 82 % of molybdenum into a rough bulk concentrate. Tests with CMC application at the selection cycle revealed a potential opportunity to reduce 1.5–2.0 times the summary sodium sulfide consumption, to cut down running costs of pulp and depressant heating, and to improve molybdenum recovery with no negative effect on other parameters of the bulk concentrate selection.
