A process for recovering a target metal from an oxidised metalliferous
material comprises the steps of: in an acid generation stage, adding
sulfuric acid to a solution comprising a metal halide to generate an
acidic aqueous halide solution; in a leaching stage that is separate to
the acid generation stage, leaching the oxidised metalliferous material
with the acidic aqueous halide solution to leach the target metal into
solution; passing the solution from the leaching stage to a target metal
recovery stage in which the target metal is recovered from the solution
whilst the metal halide is retained in solution; and returning the
solution with the metal halide therein from the target metal recovery
stage to the acid generation stage.
