A method of recovering rhenium (Re) and other metals from Re-bearing materials in the form of ammonium perrhenate having at least the step of adding Re-bearing materials into a leaching slurry. Additionally, the method has the step of adjusting the pH of the slurry to obtain Re in soluble form in a metal salt solution and insoluble residues; filtering the metal salt solution to remove the insoluble residues; selectively precipitating Re from the metal salt solution; filtering the Re precipitate from the metal salt solution to obtain a Re filtercake; and formulating and drying the Re filtercake to obtain a Re sulfide product. The method further has the step of combining the Re sulfide product with a Molybdenum (Mo) concentrate containing Re to obtain a Mo/Re concentrate; roasting the Mo/Re concentrate to obtain Mo oxide product and a flue gas containing Re; and treating the flue gas containing Re to obtain ammonium perrhenate.
