Abstract
1374851 Extraction from copper-iron sulphides COMINCO Ltd 8 Feb 1972 [19 Feb 1971] 5912/72 Heading C1A Copper-iron sulphides are treated to extract copper values and elemental sulphur therefrom in a process comprising the steps of: (1) feeding said sulphides into and reacting with an acidic CuSO4 soln. at 90‹ to 180‹ C., said solution containing Cu<++> ions in a molar ratio relative to the soluble iron in the sulphides of 0À5 : 1 to 1À5 : 1 for the production of insoluble CuS and a soln. of FeSO4; (2) separating the CuS from the FeSO4 sbln.; (3) concurrently oxidizing and hydrolysing the FeSO4 to precipitate Fe compounds and to regenerate H2SO4; (4) separating the precipitated Fe compounds from the regenerated H2SO4; (5) subjecting the insoluble CuS to an oxidizing leach in H2SO to oxidize sulphide S to elemental S and to dissolve copper as Cu<+><+> to form a copper-bearing soln. ; and (6) separating elemental S and residual solids from the copper bearing solution. Step 1 preferably takes place at a pH of 0À5-2À0, a temperature of 120-160‹ C. and under autogenous pressure. Step 3 is preferably carried out at 180-230‹ C., at 50-200 p.s.i., and with a ferrous iron concentration in the feed of 40 g./l. or less, optionally in the presence of NH4OH, NaOH or Na2SO4 to precipitate a double sulphate. The regenerated H2SO4 may be used in step 5, which may be effected in 2 or more stages at a pressure of up to 400 p.s.i. and at a temperature of 70-110‹ C. In step 6, the mixture may be separated by froth flotation to produce a a concentrate containing elemental S, metal sulphides and precious metals from which the S may be separated by melting Fe<3+> in the Cubearing solution may be reduced to Fe<2+> and the resulting solution subjected to H2 reduction or electrowinning to produce metallic Cu and acid solution which may be recycled to steps 1 and 5. Part of the Cu bearing solution from step 5 may also be recycled to step 1.
