摘　　要：为了降低一浸终液残酸量和便于处理高铁闪锌矿,冶金工作者开发出了二段加压浸出工艺。但新工艺的完善需要理论的跟进。铁在加压浸出中的行为,一直是加压酸浸理论的重难点。而二段加压酸浸中铁的行为,国内外尚没相关正式研究报告。本文通过设计试验,对铁在二段加压酸浸中的行为进行了浅析,特别是研究了第二段加压浸出中铁的浸出行为。In order to reduce the remains acid in final lixiviation liquid of first step leaching, and convenient for treating with marmatite, metallurgist invented two-steps pressure leaching process. But the perfect of new technique needs the theory to follow-up. The behavior of iron in pressure leaching is a focus in theory. And the reports about it can＇ t be seen at home and abroad. In this paper some experiments was designed to analysis the behavior of iron in two-steps oxygen pressure acid leaching, especially in second step pressure leaching.
