摘　　要：研究了在微波场下用C和S iC作还原剂时,氧化锌在精矿粉中的还原率,以模拟钢铁企业冶金含锌尘泥中锌的去除。结果表明:微波处理冶金含锌尘泥,脱锌反应快,效果显著,并且S iC作还原剂时效果较好,得到的氧化锌纯度可达97.7%。因此,微波处理钢铁企业冶金含锌尘泥是可行的。The percent reduction of ZnO in concentrate powder under the action of microwave field was researched by use of C and SiC as reducing agents. The purpose of this research is to imitate zinc-removal process from zinc-containing metallurgical dusts in the iron and steel works. The research results showed that the zinc-containing dusts can be effectively treated with the help of microwave field, and the zinc-removal process is quick. Furthermore,when the SiC is used as a reducing agent, the zinc-removal result is better than those when the C is used as a reducing agent. The purity of ZnO obtained can reach 97.7%. Therefore,removing zinc from metallurgical dusts of iron and steel works is practicable.
