摘要
湿法炼锌除铁工艺中，采用赤铁矿法除铁产出的赤铁矿渣，通过焙烧，其主要杂质指标S、Pb、Cu、As、Sn、Zn可以达到炼铁原料铁精矿标准。
In this study, the process for removing impurities from hydrometallurgy zinc hematite residue have been re- searched. The results show that under 1200℃ with 15% metallurgical coke powder for roasting 3hours the main impurities （such as S, Pb, Cu, As, Sn and Zn） of hematite residue can be remove and the roasting production can meet the standard of iron ore concentrate.
