1. Introduction Solsk is located in Khakas, Eastern Siberia, Russia. It was put into operation in 1952 and the current production scale is about 20 kt/d. Figure 1 Solsk copper-molybdenum mixed flotation process The copper-molybdenum sorting and copper selection process is shown in Figure 2. The copper-molybdenum mixed concentrate is re-milled in three stages (mixed concentrate, secondary selected concentrate, 5 selected concentrates) and 8 selected processes. Sodium sulfide is used to inhibit copper minerals, and qualified molybdenum concentrate is obtained. mine. The copper-molybdenum sorting sweeping tailings enters the copper selection circuit through a coarse, one sweep, two-selection process to obtain a qualified copper concentrate and produce waste tailings. Figure 2 Solsk copper-molybdenum sorting process 4. The mineral processing agent system is shown in the table below. Table Solsk Concentrator Chemicals System Continued on the table Note: Water glass is the consumption per ton of mixed concentrate in priority flotation, and xanthate is the consumption per ton of copper concentrate in copper flotation. 5. The ore dressing index is 0.25% Mo, the first coarse grinding fineness is 40%-200 mesh, the molybdenum concentrate grade is 48% Mo, the molybdenum recovery rate is 88.7%; the copper concentrate grade is 15.3% Cu, and the copper recovery rate is 42%. Tailings grade 0.0056% Mo, 0.0722% Cu; power consumption: 18kw·h/t mine, water: 2.5m3/t mine, steel ball: 1.559kg/t mine, liner: 0.156kg/t mine.

2. Mineral deposits, ores and mining Solsk are reticular copper - molybdenum deposits, ore-bearing breccia-type ores and disseminated metamorphic rocks, with a ratio of approximately 1:1. The main metal ore minerals molybdenite, chalcopyrite, iron, molybdenum, China, covellite, chalcocite. Non-metallic minerals are mainly quartz . The ore reserves in the deposit are about 10 Mt, the ore contains about 0.25% molybdenum, and the amount of molybdenum metal that can be recovered is about 15 kt (according to the first annual review). The plant currently only processes sulfide ore. The oxidized ore heap will not be disposed of temporarily. Open pit mining technology for mines, the largest nugget is 1200mm.
3. The beneficiation process is designed as a three-stage, closed-circuit crushing process, which has been transformed into a four-stage, closed-circuit crushing process. The ore is broken from -1200mm to -25mm (42%-8mm). The process of copper-molybdenum mixed flotation is shown in Figure 1. The ore is coarsely ground, coarsely selected, once cleaned, and twice selected to obtain a copper-molybdenum mixed concentrate. The coarse grinding fineness is 60%-200 mesh.
