8 Renium distributin in different parts f Sarcesme s enricment cycle f Cu-M 1,2 A. R. Mamudian, 2 S.K. Sadrnezaad, 1 F. Krupi, 1 S. Zeid Abadi 1 Material Eng. Grup, Islamic Azad University f Sirjan Sirjan, Iran 2 Department f Materials Science & Engineering, Sarif University f Tecnlgy Teran, Iran Abstract Renium is ne f te rarest elements in te eart s sell, wic is te byprduct f Mlybdenit, and wic in turn is te byprduct f Cpper. 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.
