Abstract

Despite being a very scarce element, the remarkable physical and chemical properties of rhenium render it a highly demanded commodity for advanced applications in important industrial fields, therefore increasing its economic value. The research project MinReMol was conceived to highlight the minerochemical behavior of rhenium in molybdenite (main natural carrier) and to improve the valorization of mineral resources, aiming at a sustainable recovery of valuable metals from old mining debris. A synopsis is presented on the main lines of action and obtained results, focusing particularly on the identification of molybdenite polytype, on rhenium speciation in the carrier compound (mineral or minero-metallurgic product) and on the implementation of a reliable methodology for the analysis of low rhenium contents.
