A High Effective Collector For Flotation Of Molybdenum ...

YX091 is an effective collector for the flotation of copper, gold, silver, zinc, molybdenum sulfides. The collectivity of YX091 to pyrites is weak. But its selectivity to copper, gold, silver ores is good. In the flotation process, YX091 displays strong collectivity, good selectivity, low dosage and some frothing property. Specification. More.
