玻利维亚某矿金钴多金属矿石工艺矿物学研究

通过对玻利维亚某金钴多金属矿石的工艺矿物学研究，查清了原矿物质组成，矿石的结构构造和金、钴、铜、铋的赋存状态。金载体矿物为硫（辉）钴矿、黄铜矿、辉铋矿。银金矿和硫（辉）钴矿包裹于毒砂矿物中，单体解离困难，只能以毒砂精矿回收，铋以辉铋矿的形式包裹于黄铜矿和毒砂中，可以在回收毒砂和黄铜矿过程中综合回收。

Process mineralogy study on Au-Co polymetallic ores from a mine in Bolivia

By means of the process mineralogy researching of Au-Co polymetallie ores from a mine in Bolivia, the mineral composition, texture and structure of the ore, as well as the occurrence forms of Au, Co, Cu, Bi were found out. The gold bearing minerals are linnaeite, chalcopyrite, and bismuthinite. Electrum and most of linnaeite （cobahite） are contained in arsenopyrite which is hard to be dissociated and can only be recovered as arsenopyrite concentrate. While bismuthinite is contained in chalcopyrite and arsenopyrite can be recovered in the process of recovering chalcopurite and arsenopyrite.
