Abstract: A copper mine in Bolivia has high copper grade and great economic value. In order to exploitand utilize this resource, the process mineralogy of the representative mineral was studied. The resultsshowed that: ()The main textures of the ore are mainly sparse disseminated texture and massive beddingtexture. The main structures in the ore are mainly gravelly unequal grain sand structure, xenomorphicgranular structure,interstitial structure, metasomatic residual structure. 2)The copper grade is 4. 98%and 94.61% copper is copper oxide, which mainly occurred in minerals such as cuprite, malachite.chrysocolla, delafossite and native copper. 3)The copper in the ore can be recovered by using enhancedsulfide flotation and hydrometallurgy. lt is necessary to comprehensively analyze the results of beneficia-tion and metallurgical test and production cost for judgment and decision-making.
