Abstract
Nickel, copper, and elemental sulfur can be recovered from a low-grade pyrrhotitepentlandite type concentrate by leaching with HNO3 in a pressure reactor at moderate temperature and pressure. The bulk of iron is converted to an oxide. Same results can be achieved by leaching in an open vessel under a reflex condenser for an extended period of time.
