Abstract

Copper is separated from a molten nickel-copper sulphide material by liquid-liquid extraction with a molten mixture of sodium sulphide and sodium chloride, preferably containing 25 to 75% by weight of sodium chloride. The amount of molten salt mixture used is generally from one half to twice the weight of the nickel-copper material, and the sodium chloride may be wholly or partly replaced by one or more of potassium, calcium or aluminium chlorides. In Example 1, 150 g. of a nickel-copper matte containing 68-2% Ni and 3.25% Cu was mixed with 150 g. of sodium sulphide and the mixture melted in a crucible at 845 DEG C., the upper sodium-rich and the lower nickel-rich fractions being tapped from the bottom of the crucible into separate containers and analysed. In Example 2 a nickel matte containing 3.25% Cu was treated for copper extraction by a multi-stage countercurrent liquid-liquid extraction at 845 DEG C., the solvent being 50% by weight of sodium sulphide and 50% by weight of sodium chloride. The final copper-rich solvent had a nickel-copper ratio of 0.3 : 1 and the final nickel sulphide had a nickel-copper ratio of 2110 : 1. Example 3 is similar except that the countercurrent extraction was conducted at 760 DEG C. The counter-current extraction is preferably carried out continuously in a liquid-liquid extraction column which is provided at intervals with solid baffle plates each of which is formed as a tray with a lip and extends part way across the column cross-section. Molten sodium salt solvent is introduced into the lower part of the column, copper-rich solvent is drawn off from the top and nickel-sulphide from which copper has been eliminated is drawn off from the bottom of the column. Specification 960,698 is referred to.
