摘　　要：玻利维亚某铜矿石铜品位较高,经济价值大,为了能够更好地开发利用该资源,对有代表性矿石进行了工艺矿物学研究。结果表明:①矿石的构造主要有稀疏浸染状构造和块状层理构造;矿石的结构主要有砾质不等粒砂结构、它形粒状结构、填隙结构、交代残余结构等;②矿石含铜4.98%,氧化铜占总铜的94.61%,主要赋存在赤铜矿、孔雀石、硅孔雀石、铁铜矿及自然铜等矿物中;③矿石中的铜采用强化硫化浮选和湿法冶金两种方法均可回收,需综合分析选冶试验结果及生产成本进行判断和决策。A copper mine in Bolivia has high copper grade and great economic value.In order to exploit and utilize this resource,the process mineralogy of the representative mineral was studied.The results showed that:①The main textures of the ore are mainly sparse disseminated texture and massive bedding texture.The main structures in the ore are mainly gravelly unequal grain sand structure,xenomorphic granular structure,interstitial structure,metasomatic residual structure.②The 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.③The copper in the ore can be recovered by using enhanced sulfide flotation and hydrometallurgy.It is necessary to comprehensively analyze the results of beneficiation and metallurgical test and production cost for judgment and decision-making.
