摘　　要：分析内蒙古赤峰某锌冶炼厂酸浸出-沉矾工艺中沉矾渣、高酸渣渣锌偏高以及沉矾后液铁含量偏高的问题。通过采用相应的技改优化措施,不仅降低了沉矾渣与高酸渣的锌含量,同时通过调整辅料加入方式,使沉矾分梯度进行,也降低了除铁后液铁浓度,减少了辅料用量,优化措施实施后产生了可观的经济效益。The problems of high zinc contents in the jarosite precipitation slag and high-acid slag, in the acid-leaching and jarosite-precipitation process in a zinc smelter in Chifeng city, Inner Mongolia were analyzed. By the adoption of respective improvement measures, the zinc contents in the jarosite precipitation slag and high-acid slag was reduced. Meanwhile, by adjusting the feeding way of the supplementary materials to make jarosite precipitation gradiently, the iron concentration liquid after iron removal was reduced with reduction of supplementary materials consumption. Significant profit has been achieved after the implementation of the optimization measures.
