Abstract
Cobalt and nickel hydroxides are obtained from silicate ores or metallurgical waste containing at least 0.15% nickel by mixing ore or waste with sulphur or sulphides, sulphates or sulphites of other metals and with chlorides or alkali or alkaline earth metals, roasting so that the nickel and cobalt are converted into water-soluble chlorides, oxychlorides or chloride-sulphate mixed salts, leaching with water, aqueous ammonia or dilute aqueous acid, and selectively precipitating nickel and cobalt from the solution as hydroxide. Chlorination and sulphation are effected simultaneously by adding one or more of the following compounds:-FeS2, FeS, FeSO4, S, together with NaCl and/or CaCl2 and roasting at a temperature from 250 DEG to 600 DEG C. The roasted material may be leached with the solution obtained by absorbing the roaster gases in water. Insoluble silicates separate out to leave a solution containing nickel, cobalt, iron, manganese magnesium and sodium sulphate. Sodium sulphate may be recovered on cooling. The metals are recovered by one of two methods; in one method, iron cobalt, manganese and nickel may be selectively precipitated as hydroxides at progressively increasing pH from 4-8 under oxidizing conditions. In the other method, the nickel, cobalt, and iron may be precipitated from the solution using alkali metal or alkaline earth metal hydroxides, or milk of lime; the ferrous iron is oxidized to ferric by aeration and the nickel and cobalt compounds are dissolved in acid at a pH above 4 and reprecipitated at a pH value of less than 6. Nickel and cobalt may be precipitated as the tetravalent hydroxides by means of calcium, sodium or potassium hypochlorite, or sodium hydroxide. Magnesium hydroxide may be precipitated at pH 9-10 from the solution remaining after precipitation of the nickel and cobalt hydroxides.
