摘要
铼是难熔金属，主要赋存于斑岩铜钼矿床的辉钼矿和黄铜矿中，铼含量在20～2000g／t之间。从钼精矿焙烧产出的烟尘和淋洗液中回收铼及从钼精矿氧压氧化浸出液中回收铼多采用溶剂萃取法和离子交换法。铼用作制取各种催化剂，如汽油重整、烯烃复分解等。铼也用于生产钼铼合金、钨铼合金、镍基超合金和铌铼合金等。铼的某些配合物用作抗癌药物。
Rhenium is refractory metal which mostly distributes in molybdenite and copper sulphide of porphyry Cu - Mo deposite with rhenium concentration 20～ 2 000 g/t. Solvent extraction and ion exchange process were mostly adopted to recover rhenium from smoke and washing water produced in molybdenum concentrates roasting and leac- hing solution of oxygen pressure oxidation for molybdenum concentration. Rhenium is mostly used for catalysts, sueh as reforming catalysts, olefin metathesi catalysts and ect. Rhenium is used for producing Mo - Re alloy, W - Re al- loy, nickel based superalloys and Nb - Re alloy and etc. Rherium complexes are also used for antieareinogen.
