A bulk sulfide flotation process followed by oxidation pressure leaching resulted in high extractions (gt;98 %) of the copper and nickel in the flotation concentrate. During the leaching, the iron in the flotation concentrate leaches and precipitates as either hematite (crystalline or amorphous) or as a basic iron sulfate (jarosite).
