| Abstract | (Summary)
The copper concentrate received from McIntyre Porcupine Mines contained approximately 0.6% MoS?. The molybdenite occurred mostly as free grains varying from 5 to 60 microns in size,
but occasionally was intergrown with chalcopyrite. Phosphorus pentasulphide or arsenic trioxide were both found to be suitable for separating the molybdenite from the copper minerals by selective flotation. The latter proved to be slightly more
effective and was used in a test incorporating four cycles of flotation. This. technique produced a concentrate assaying 73.2% MoS? and 3.5% Cu with a molybdenite recovery of from 60% to 78%. Attempts to upgrade the rnolybdenite concentrate to 90%
MoS? were unsuccessful. Other reagents such as sodium cyanide and ferrocyanide were found to be ineffective in separating the molybdenite from the copper minerals. |
