The study the possibility of using waste from wine-alcogol production of by the selective separation of collective copper-lead concentrate

Abstract

Currently one of the priority objectives in the field of flotation retreatment of complex ores are exploration and the development of effective and selective chemical reagents in order to increase an extraction of valuable components and expenses reduction per output unit. Practical experience of flotation shows that the process diagrams of receiving a collective concentrate of non-ferrous metals with their further selective separation to obtain a lead, copper, zinc concentrate are applied to extract the non-ferrous metals concentrates out of complex ores. The efficiency of selective separation of collective concentrates depends on the range of flotation reagents in many respects. The paper includes the studies of a collective copper-lead concentrate applicability of alcohol waste from «Bacchus» JSC under selective separation. A liquid waste compound was studied for the purpose and sulfite ions content was established that allows replacing sodium sulfite at selective separation of copper and lead by sulfite technology.A complex ore of Artemjevsky deposit was used as an initial matter at the selective flotation separation; the ore contains copper 1.6%, lead 2.6%, zinc, 7.2%, iron 7.8%. The flotation circuit includes a copper-lead cycle with the receiving of a collective copper-lead concentrate and a selection cycle for collective copper-lead concentrate. The waste is used instead of sodium sulfite in the cycle of selection of collective copper-lead concentrate. The liquid waste of alcohol production allows replacing the basic reagent sodium sulfite, at simultaneous keeping of technological parameters of floatation enrichment and contributes expenses reduction for complex raw materials retreatment.
