摘要: The present invention is directed to the treatment of sulfide materials containing nickel and/or copper sulfide but substantially free of iron to recover the metal values as a sulfate solution and to liberate elemental sulfur wherein the metal sulfide is slurried in an aqueous sulfuric acid-iron sulfate leach solution and is then heated at a temperature range of about 80* C. to 150* C. under an oxygen partial pressure of at least about 2 atmospheres to dissolve the metal values and liberate elemental sulfur.
