拉拉铜矿铼的分布和潜在资源利用意义

The Distribution of Rhenium in the Lala Copper Ore and Its Potential Significance of Resources

拉拉铜矿是四川省最大的铜矿,并且产出数量可观的钼。本文利用等离子质谱(ICP-MS)分析了拉拉铜矿辉钼矿的铼含量,结合前人报道的黄铜矿和辉钼矿中铼含量数据,讨论了拉拉铜矿铼的赋存分布特征,针对性分析了潜在资源价值。辉钼矿中铼含量较高,但不同产状矿石的辉钼矿Re含量变化较大。黄铜矿的铼含量远远低于辉钼矿的铼含量。因此,拉拉铜矿铼主要赋存于辉钼矿和黄铜矿中,二者均具有潜在的经济价值。此外,世界上其他一些典型的铁氧化物铜金矿床也不同程度的富集铼,该类矿床可能将是未来世界铼的潜在资源。

The Lala copper ore with considerable molybdenum is the largest copper one in Sichuan province. We de-termine the concentration of rhenium in molybdenite using ICP-MS and summarize the previous data of rhenium con-tents in molybdenite and chalcopyrite and discuss the distribution of rhenium and its potential significance of re-sources. The rhenium contents in molybdenite are high and variable in different ores. The rhenium contents in chal-copyrite are much less than those in molybdenite. Thus, the rhenium most distribute in molybdenite and chalcopyriteand both have potential economic values. Furthermore, iron oxide copper gold deposits may represent a potential sig-nificant source of rhenium in the future.
