    Ni-sulphides only carried 35% to 45% of nickel. The high percentage of Ni carried by silicates is expected to lead to poor flotation recoveries. The electron microprobe analysis also revealed a high Ni content in pyrrhotite at 0.81%, suggesting that recovering pyrrhotite intentionally in flotation is likely able to improve Ni recovery.
