description A method of smelting a nickel intermediate product in a smelter that contains a molten bath of metal and slag to produce a nickel product, the method comprising supplying the nickel intermediate product and a solid reductant to the smelter and smelting the nickel intermediate product to produce molten nickel, and controlling the chemistry of the slag so that the slag has (a) a high solubility for elements and compounds in the nickel intermediate product that are regarded as contaminants in the nickel product and (b) a liquidus temperature in the range of 1300-1700 C.
