铼是最稀少的非放射性元素之一,尚未发现有原生铼矿床存在。在北美洲、南美洲和小亚细亚的铜/钼斑岩矿床中存有大量的铼。其次,在非洲铜带和苏联的沉积铜矿床中也发现有铼。
Rhenium is one of the rarest non-radioactive elements and no native rhenium deposit has been found. In North America, South America and Asia Minor copper / molybdenum porphyry deposits are abundant in rhenium. Second, rhenium was also found in copper deposits in Africa and in the Soviet Union’s sedimentary copper deposits.
