ABSTRACT:
Metal values may be recovered from metal bearing sources which contain at least two metals, at least one of which is in the form of a sulfide, by treating the aforesaid source with a mild oxidant at an elevated temperature in the range of from about 600.degree. to about 1500.degree. C. whereby at least one metal value is converted to an oxide and at least one metal value is converted to the elemental state which contains a relatively minor amount of sulfur. Thereafter the metal compounds may be separated and recovered by conventional means.
