Fursman2 SUMMARY These investigations were conducted to determine conditions for recovery of nickel and copper from Funter Bay, Alaska, sulfide ore and recovery of nickel from nickelsilie ore, Nickel Mountain, Riddle, Oreg. Samples of

The flotation of magnetic and nonmagnetic pyrrhotite from

Nonmagnetic pyrrhotite was less reactive in terms of its oxygen uptake and showed the best collectorless flotation recovery. Magnetic pyrrhotite was more reactive and showed poor collectorless flotation performance that could be improved with the addition of xanthate collector, but only if it was not already passivated.
