<p>Disclosed is a method for separating copper from copper bearing materials comprising the steps of: (a) subjecting a copper bearing material to a bioleach step involving iron/sulphur oxidising microorganisms to form a bioleach solution containing copper; (b) at least partially removing separated copper from the solution by contacting the solution with a copper extracting organic solvent; and (c) recycling at least part of the copper depleted solution to the bioleach step.</p> |
