中文摘要：

在室温和pH值为中性的开放体系下，选用川滇黔地区与峨眉山玄武岩自然铜矿床相关的不同类型矿物，对配制的铜胶体溶液和cu^2＋溶液进行吸附试验，结果表明，矿物对铜胶体和cu^2＋的吸附率从高到低分别为硫化物、有机质（沥青）、粘土矿物、硅酸盐矿物。这一实验结果与川滇黔地区自然铜矿的赋矿围岩为玄武质角砾岩、铝土一粘土质沉积岩，自然铜与有机质伴生等地质现象一致，并表明有机质在自然铜成矿作用中不仅提供了还原条件，而且是很好的吸附剂。文章还探讨了与峨眉山玄武岩有关的自然铜矿床中铜的迁移形式：认为铜不仅能以离子或络合物的形式迁移，还可能以纳米粒级单质铜的形式迁移。

英文摘要：

This study selected deferent minerals from Emeishan basah-related native Cu deposits in the Sichuan-Yun- nan-Guizhou area for colloid Cu and Cu2＋ solution adsorption investigations under room temperature and neutral pH conditions. Adsorption rate of colloid Cu and Cu2 ~ solution by different minerals decreases according the order of sul- fides, organic matters （bitumen） , clay minerals and silicates. The adsorption result is consistent with the fact that n- ative Cu in the Sichuan-Yunan-Guizhou area is mostly hosted in basaltic breecias and aluminous-clayey sedimentary rocks. Native Cu is generally associated with organic matters, which are ideal adsorbent, indicating reducing condi- tions during ore forming stage. This study also discussed Cu migrating ways in the Emeishan basalt-related Cu depos- its. Cu can migrate not only in forms of ions or complexes, but also in nanometer-level simple substances.
