Iron removal from zinc liquors originating from hydrometallurgical processing of spent Zn/MnO2 batteries

Popis výsledku v původním jazyce

In this work, the removal of iron from leach liquors obtained after processing of spent alkaline and zinc-carbon Zn/MnO2 batteries with initial iron ion concentration in the range of 270 to 580 mg/L has been studied. Solid Na2CO3, ZnO and fine ground waste electrode materials separated from processed Zn/MnO2 batteries were tested as precipitation agents. All used precipitation agents make it possible to remove more than 99% Fe, but electrode materials have been found to be more efficient precipitants atlower pH values. The different course of iron precipitation is probably caused by different solubility of iron compounds formed during the precipitation with various precipitation agents. Precipitates in which iron was present as FeO(OH) originated fromprocessing the leach liquors with Na2CO3 or ZnO Precipitates from processing the leach liquors with electrode materials contained zinc-iron non-stoichiometric oxides, which was established as results of experiments performed with a synth
