to place in the same deposit. The low nickel content of the present-day nickel sulRde ores renders them unsuitable for either direct smelting or hydrometal-lurgical extraction, thus requiring beneRciation. The usual method of nickel extraction from sulRde ores is through the production of nickel matte after enriching the nickel content of the ore.
