Abstract
In the extraction of non-ferrous metal values particularly of Ni, Co, or Cu from materials containing them by means of an oxidative sulphate leach, the sulphur content of the initial material is adjusted and the mixture is smelted to form a matte having a sulphur content to produce, after oxidation, an amount of sulphate ion greater than, and up to 100% in excess of, the amount required to combine with non-ferrous metal values; the so obtained matte is then ground to a particle size of from 0.417 to 0.043 mm. and reacted with an aqueous sulphuric acid solution in the presence of a free oxygen containing gas at a temperature from 90 to 180 DEG C. until the non-ferrous metal values have dissolved. Oxygen partial pressures from 0.5 to 7 atmospheres are preferred, or if air is used a total pressure from 5 to 9 atmospheres and a temperature from 120 to 150 DEG C. is suitable. The leach solution should contain 0.05% sulphuric acid at least. According to a typical example a ferro-nickel-cobalt alloy was smelted in a carbon are furnace with nickel sulphide to form a matte containing the required amount of sulphur. Pyrites may be similarly employed. The matte obtained was ground and leached.
