第二次世界大战以前,德国首次从铜熔炼厂的残渣中生产铼,美国在1942年也从辉钼矿焙烧炉的烟尘中生产出铼。目前,从矿石中回收铼的主要矿石资源国家有加拿大、智利、美固、苏联。智利是世界铼的主要提供国之一,并可继续扩大提供量,美国虽然有很大的铼储量,由于国内铼产量下降,仍需进口很大数量的铼。 Prior to the Second World War, Germany produced rhenium for the first time from the residue of a copper smelter, and in 1942, the United States produced rhenium from soot from the molybdenite roaster. At present, the major ore resources for recovering rhenium from ore are Canada, Chile, United States and the Soviet Union. Chile is one of the major suppliers of rhenium in the world and can continue to expand its supply. Although the United States has a large rhenium reserves, it still needs to import a large amount of rhenium due to the drop in domestic rhenium production.
