本发明是关于从一种含有杂质的铼原料中回收高纯徕的方法。特别是关于制取高纯铼化合物的方法。此法消除了金属本身至今为止难于除去金属杂质的现象,把原来在一种有效装置中可以看到铼原料中杂质的存在,降低至先前任何方法所不易达到的最低水平。到目前为止,已经推荐了几种以净化的方式来回收铼的方法,但是先前所采用的那些 The present invention relates to a method for recovering high purity tin from an impurity rhenium starting material. Especially on the preparation of high purity rhenium compounds. This method eliminates the metal itself so far difficult to remove the phenomenon of metal impurities, the original device in an effective rhenium can see the presence of impurities in raw materials, reduced to any previous method is not easy to reach the lowest level. So far, several methods have been proposed for the purification of rhenium, but those previously employed
