are difficult to achieve high degree of purification. Because of large difference between the leaching process of the zinc oxide ore and the traditional zinc calcining in the cycle of leaching solution and solution chemical conditions, the traditional purification process is not suitable for the disposal of zinc oxide ore leaching solution [1-2]. However, the extractive purification of zinc from zinc oxide......
