摘　　要：选用4种铜矿进行混合矿模拟冶炼黄铜对比试验,并利用X射线衍射、X射线荧光、金相显微镜、扫描电子显微镜和电感耦合等离子发射光谱等技术对矿石、黄铜样品和试验残渣等进行检测分析.结果表明,4组模拟试验获得的黄铜主要含铜、锌和铅3种元素,含锌17％～28％（与目前已发现的早期黄铜含锌量相当）,其他元素含量均小于0.1％,金相组织均为等轴晶和孪晶.Four kinds of copper ores of malachite were chosen to simulate smelting of brass.The raw materials,brass samples,and smelting residues were detected and analyzed by XRD,XRF,metallographic microscope,SEM,and ICP.The results show that main content of brass obtained from four kinds of copper ores includes copper （71％～82％）,zinc （17％～28％） and lead （0.4％～1.1％）.The content of other elements is no more than 0.1％.The microstructures of brass are isometric crystal and twin crystal.
