Abstarct: Molybdenite concentrates are the major source of Rhenium in the world. It has about 500-900 ppm Rhenium content. In the roasting process of molybenite, rhenium in the form of gases and dust accumulate in the scrubber and filters with an average grade of 3000 ppm. In today’s world, Rhenium has a special place in space and aviation industry, petroleum and radio medicine. Sarcheshmeh copper mine has a big potential for rhenium recovery baxsed on its high rhenium content in molybdentite concentrate and also high price of rhenium mextal and its compounds in market. In this study, a review of technologies used worldwide is presented and recommendations are set up to be used in Sarcheshmeh for Rhenium recovery. In this thesis, first of all possibility of selective leaching of rhenium over molybdenum was investigated. It is found that Effect of temperature is one of the most important parameters in leaching process. Also it is found that addition of alcohols to leachate causes a better separation of Mo and Re, although with increasing of alcohol content of leachate, transfer of both mextals to aqueous phase face decreasing. At last, extraction of Re and Mo from aqueous phase studied using organic solvents like TOA, TBP and their synergism.
