US3652265A - Recovery of metal values from nickel

A process for recovering nonferrous metal values from nickelcopper mattes includes the selective separation of nickel from the mattes by oxidative pressure leach of the matte and equilibration of the pressure leached material to a pH of preferably 5.35 + OR - 0.3. Thereafter copper is leached from the resultant nickel depleted residue under relatively mild conditions.
