Abstract

Using the differencing of temperature dependence of reducibility between zinc and iron oxides, the principle of a zinc extraction process named the 'Iron-Reduction Distillation Process', which consists of the reduction of ZnO by previously-reduced iron, was proposed and this possibility was confirmed experimentally. This process consists of two stages of reduction for a mixture of iron oxide as a starting material. On the second reduction at a higher temperature, zinc oxide was easily reduced by metallic iron under vacuum. When the second reduction was successfully carried out after the first reduction, distillation of zinc proceeded faster; at 1373 K, for example, all of zinc was distilled within 20 minutes. By successive treatment of the first and second reductions, 93 to about 99% zinc recovery was obtained and iron content in residue was 87 to about 92%.
