Abstract
The invention relates to a process for leaching metals from metal sulfide ore and/or concentrate, comprising: electrolytically generating a leach solution of oxidative halogen-based lixiviant; contacting the metal sulfide ore and/or concentrate with the leach solution of oxidative halogen-based lixiviant to produce a metal-bearing solution; and passing the metal-bearing solution to metal separation.

An apparatus for leaching metals from metal sulfide ore and/or concentrate, comprising:
- a halogen generator, wherein the halogen generator electrolytically generates a leach solution of oxidative halogen-based lixiviant;
- a leach environment where the metal sulfide ore and/or concentrate is contacted with the leach solution of oxidative halogen-based lixiviant to produce a metal-bearing solution;
- and
- means for metal separation from the metal-bearing solution.
