  • COPPER RECOVERY FROM LEAN SULFIDE ORES

    Oct 01, &#; Copper is recovered from ores containing about 10-15 percent copper in the form of a sulfide in the presence of significant amounts of iron and nickel, by sulfatizing roasting the ore in an atmosphere including 5-15 percent SO 2 at a temperature of from about 580°C to about 625°C and leaching soluble copper salt therefrom with water.
