摘要：
This report submits data of high-efficiency methods for rhenium recovery from secondary raw materials of various types, such as exhausted platinum-rhenium catalysts and scraps of rhenium-containing molybdenum, tungsten and nickel based alloys. Developed methods are used on a commercial level at industrial enterprises of Russia and CIS. A process for selectively recovering rhenium from exhausted Pt-Re catalysts includes the following steps: roasting, acid- or alkali-assisted leaching, ion-exchange recovery of rhenium from the solution and preparing high-purity ammonium perrhenate (99.99%). Results of developing commercially applicable methods are useful for rhenium recovery from scrap of rhenium-containing alloys.
