RECOVERY OF METALS FROM OXIDISED METALLIFEROUS MATERIALS |
摘要 |
<p>A process for recovering a target metal from an oxidized 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 oxidized 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 while 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.</p> |
