Production of metallic nickel with low iron content |
| abstract |
A process for producing a metallic nickel product with a low iron content, including the steps of: (i) providing an acidic product liquor containing at least nickel and iron; (ii) subjecting said acidic product liquor to an ion exchange process wherein an ion exchange resin selectively absorbs said nickel and part of the iron from said product liquor; (iii) eluting the nickel and iron from said resin with an acidic solution to produce an eluate containing said nickel and iron. (iv) neutralising said eluate to a pH value in the range from 2.5 to 3.5 to cause precipitation of a substantial amount of said iron, leaving an iron depleted eluate; (v) neutralising the iron depleted eluate to a pH value in the range from 7 to 8 to cause precipitation of nickel hydroxide containing low iron; (vi) calcining said nickel hydroxide to convert it to nickel oxide; (vii) subjecting said nickel oxide to direct smelting in the presence of a reductant to produced a molten nickel phase; and (viii) refining said molten nickel phase by oxidation to produce a metallic nickel product with low iron content. |
