  • role of sodium hexametaphosphate in flotation of a nickel ore

    The nickel grade of the ore sample used in this study was 1.35%. Approximately 96% of the nickel in the ore was in the form of pentlandite, and could be recovered by true flotation. The remaining 4% of nickel distributed in non-sulfide minerals, which could only be recovered by the entrainment mechanism or as composites with pentlandite.
