还原焙砂
Decomposing zinc ferrite to zinc oxide and ferroferric oxide selectively under reduction atmosphere was proposed, and acid leaching and magnetic separation processes were carried out to separate zinc and iron from reduced zinc calcine according to their characteristic difference.
本研究拟在弱还原气氛下将锌焙砂中的铁酸锌选择性分解为氧化锌及四氧化三铁,依据二者理化性质的差异,采用弱酸浸出-磁选组合工艺实现铁锌的分离。
