The method involves magnetically separating at least a portion of any magnetic impurities from the slurry and then leaching or dissolving at least a portion of any remaining magnetic impurities in a slurry. At least one chelating agent is then be added to the slurry and the solids of said metal and/or oxide are recovered from the slurry by various separation techniques.
