  • A Pt-Re catalyst-based rhenium and platinum recovery solvolyticometallurgical technique has been developed by chlorinating with chlorine gas mixed with dimethylformamide and hydrochloric acid. The two-stage process conducted with burning residue after the first phase chlorination results in additional platinum transfer into the solution and makes it possible to obtain 70–94% platinum recovery and 91–96% percent rhenium recovery
