Conclusions. In this work, PU was used as a potential depressant for the separation of molybdenite from talc. In the flotation tests, the results showed that under the reagent scheme of 40 mg/L PU, 160 mg/L BX and 25 μL/L MIBC, the selective separation of molybdenite from talc could be achieved across a wide pH range (from pH 2.0 to pH 8.0).Web
