  • Pentlandite oxidation in the flotation of a complex

    2011-1-1 · The current study indicates that oxidation occurred on both fine and coarse pentlandite in the flotation of a complex nickel ore in saline water. The flotation of both fine and coarse fractions could be improved by adding NaHS or dithionite during grinding. However, NaHS increased serpentine flotation while dithionite did not.Upgrading nickel in laterite ores by flotation ,Nickel laterite deposits are generally divided into limonite (oxide), nontronite (clay) and saprolite (silicate) zones. A systematic study was conducted on the ore samples sourced from these three categories to see the effect of different mineralogies on the flotation behaviour of laterite ores.
