A certain copper ore in Zambia is a kind of oxidized ore with high proportion of combined phases,in which the grade of copper is 2. 10%,and grade of other associated valuable elements such as Fe,Au,Ag,and Co are 24. 20%,0. 20 g/t, 7. 60 g/t,and 0. 05% respectively. In order to determine the proper beneficiation process,study on process mineralogy of this copper ore was made. The results show that①the mineral composition is complex and the main useful minerals include hema-tite-limonite,magnetite,chalcosiderite, green chalcosiderite, pseudo-malachite and so on.②the mineral structures mainly in-clude vesicular,crumby,disseminated granular,riband-striped,circle-like,metacolloform,miarolitic,and veinlet structures,the mineral textures mainly include xenomorphic granular,cryptocrystalline,sarciniform,pectination,columnar and metasomatic.③copper in chalcosiderite,green chalcosiderite and pseudo-malachite account for 41. 03%,40. 27%,and 15. 35% of the total copper respectively. Chalcosiderite and green chalcosiderite are all cryptocrystalline aggregation with particle size of 0. 01~0. 5 mm. The particle size of pseudo-malachite is generally within the range from 0. 01 to 0. 4 mm,and few reach up to 0. 8 mm. The particle size of hematite-limonite is generally within the range from 0. 01 to 0. 5 mm,and few reach up to 4 mm. The particle size of magnetite is larger,which is generally within the range from 0. 1 to 0. 2 mm. Therefore,this kind of copper ore belongs to refractory multi-metal oxidized ore.
