摘　　要：开展了真空下铁还原高铁硫化锌精矿的热力学分析和试验研究。在整个还原过程中锌以单质形式冷凝回收,直收率达95%左右,矿物中的硫主要以FeS的形式固定。通过试验研究确定了真空下铁还原高铁硫化锌精矿较好的工艺条件。Thermodynamic analysis and experimental study on reduction of marmatite by iron in vacuum were studied. In the whole reduction process, zinc was produced in the form of element by condensing, and its recovering reached about 95% , sulfur in ore remained mainly in the form of FeS. We also present better process conditions after experimental study.
