摘要
提出了一种锌湿法冶炼赤铁矿法除铁新工艺,分析了硫酸盐溶液体系内三价铁沉淀氧化铁和二价铁沉淀氧化铁的不同之处,并对锌浸出液赤铁矿法除铁工艺的影响因素进行了分析。无论理论还是实际都证明了该工艺的可行性,预计其可以替代锌湿法冶炼工艺中传统的黄钾铁矾除铁法。
This article introduced a technology of iron removal by new process calleed hematite method in the field of zinc hydrometallurgy. The difference between the Fe2＋ and Fe3＋ precipitation mechanism was discussed. Furthermore, the factors influencing the hematite method was also studied in details. The hematite method is proved feasible, which can be a alternative to the conventional method of jarosite.
