| Abstract: | To treat a molybdenite ore with high talc content, flash flotation was adopted to remove gauges before molybdenite flotation. With a grinding fineness of -0.074 mm 90%, the ore was processed using MIBC(50 g/t) as talc collector, sodium silicate(600 g/t) as gauge depressant, kerosene(120 g/t) as molybdenite collector and 2# oil(20 g/t) as the foaming agent. With this approach, an effective separation of talc and molybdenite can be actualized, as a molybdenum bulk concentrate with molybdenum grade of 7.79% and recovery of 85.26% can be obtained. |
