拉拉铜矿铼的分布和潜在资源利用意义

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 distribution of rhenium in the Lala copper ore and its potential significance of resources

The Lala copper deposit with considerable molybdenum is the largest copper deposit in Sichuan province. We determine the concentration of rhenium in molybdenite using ICP-MS and summarize the previous data of rhenium contents in molybdenite and chalcopyrite and discuss the distribution of rhenium and its potential significance of resources. The rhenium contents in molybdenite are high and variable in different ores. The rhenium contents in chalcopyrite are much less than those in molybdenite. Thus, the rhenium most distribute in molybdenite and chalcopyrite and both have potential economic values. Furthermore, iron oxide copper gold deposits may represent a potential significant source of rhenium in the future.
