ABSTRACT:
Sulfide ores are reduced directly to metallic values such as nickel, copper and iron, by use of a scavenger such as calcium oxide to combine with the sulfur and prevent sulfurous gas from escaping into the atmosphere. The separate metals, copper, nickel and iron can then be recovered as by leaching.
