Abstract(Summary)
Flotation tests in which a rougher molybdenite concentrate was reground and given repeated stages of cleaning resulted in a final molybdenite concentrate assaying 67.6% MoS? with a recovery of 82.6% of the molybdenum in the ore. Attempts to produce a concentrate of marketable grade of over 90% .MoS? were unsuccessful due to the very fine intergrowth of the molybdenite and the serpentine mineral grains. Even ultra-fine regrinding of the above molybdenite concentrate in a Trost jet mill failed to completely liberate the molybdenite-serpentine intergrowth and resulted in a final concentrate, after refloating, of only 81.3% MoS?.
