Due t te apprpriate pysical and cemical prperties f Renium, it as imprtant applicatins in mdern industry. In tis researc, quantities f Re fr cmpsite f te first six mnt f 1383 & 1384 and secnd six mnt f 1383 & 1384 in different parts f Sarcesme s enricment cycle f Cu-M were measured. Tese cmpsites, wit respect t prduct weigt, were prepared and used, and te results were cmpared wit analyses results f Iranian Atmic Agency and Alfred K. Knigt C. f Swiss. Keywrds: Renium, Mlybdenit, Sarcesme.
