The copper is leached from the concentrate in the leach solution in the presence of an oxygen-containing gas, under conditions whereby the pyrite is substantially unoxidized. The leached copper is recovered from the solution by conventional methods. The used silver-treated pyrite is recycled to the leaching process.
