为合理制定资源开发利用方案，对库鲁兹铜矿有代表性矿样进行了工艺矿物学研究，结果表明：矿石属于含铜较高的硫化铜-氧化铜混合矿石，矿石有价成份主要为铜，其含量为2.29%，铜赋存于黄铜矿中约占29.26%，赋存于铜蓝、辉铜矿、蓝辉铜矿等占23.14%，赋存于铜氧化物含量占36.25%，赋存在硅孔雀石含量11.35%；矿石中有用矿物总体上属粗粒嵌布，但嵌布粒度不均匀。当矿石磨矿细度为-0.074 mm粒度且占70%时，黄铜矿的单体解离度67%，铜氧化物的单体解离度65%。

In the beneficiation process research in Cruz Copper ,Bolivia, a set of representative samples indicated that the ores were high copper content and a complex mixture type of sulfide copper ores and oxide copper ores. The result also indicated that the valuable element is only copper of 2.29% in grade. The content of copper is 29.26%in chalcopyrite, 23.14%in covellite, chalcocite, blue chalcocite, 36.25%in copper oxide ore, and 11.35%of chrysocolla. The disseminated relationship between useful minerals in ores was complex, generally coarse-grained and uneven granularity. The liberation degrees of chalcopyrite and oxide copper ores were 67%and 65%respectively at the grinding fineness of 70%passing 0.074 mm.
