摘要

28,201 TITLE: SOLVENT EXTRACTION PROCESS FOR THE REMOVAL OF IRON (III) FROM LEACH LIQUORS Iron (III) bearing leach liquors may be treated with an extraction solvent comprising an organophosphoric acid, a trialkyl phosphine oxide and a water-immiscible organic diluent to separate the iron (III) from the leach liquor. The iron (III) loaded extraction solvent may subsequently be treated with a strong mineral acid to recover the iron (III). as a water-soluble salt.
