Abstract: In order to provide basis and guidance for the ore dressing test of a copper and lead oxide ore in Burma， the composition， structure and texture of the ore and the embedding characteristics of the main minerals are studied by conventional mineralogical means. The results show that ①the ore contains 1.52% copper， 7.84% lead and 243.80 g/t silver， the main useful minerals are azurite， malachite， galena， cerusite and so on. The main gangue minerals are quartz， barite and calcite， and the ore mineral composition is complex. ②Copper oxide minerals account for about 85% of the total copper minerals， mainly in the form of malachite and azurite， copper sulfide only accounts for about 15% of the total copper， and the oxidation rate of lead minerals is about 65%， lead mainly in the form of galena， cerusite ore and lead alum. ③The structure of ore structure consists of cracking altered siltstone structure， hypautomorphic plate-xenomorphic granular structure， fine crystal structure， unequal granular and granular structure， metallic opaque mineral with granular structure and residual structure. Mineral aggregates in ore fragments are evenly distributed， and a small amount of azurite and malachite scattered disseminated， with massive structures and scattered disseminated structures. ④The granularity of the minerals in the ore is not uniform， usually from 0.004 to 3 mm， and the size of the copper minerals is generally 0.01 ~ 1 mm， and the size of the lead minerals is generally 0.004 to 1.5 mm.
