A METHOD FOR RECOVERING RHENIUM AND OTHER METALS FROM RHENIUM-BEARING MATERIALS |
摘要 |
The present invention relates to a method of recovering rhenium (Re) and other metals from Re-bearing materials including, as an exemplary process, the steps: (i) adding Re-bearing materials into a leaching slurry; (ii) adjusting the pH of the slurry to obtain Re in soluble form in a metal salt solution and insoluble residues; (iii) filtering the metal salt solution to remove the insoluble residues; (iv) selectively precipitating Re from the metal salt solution; (v) filtering the Re precipitate from the metal salt solution to obtain a Re filtercake; (vi) formulating and drying the Re filtercake to obtain a Re sulfide product; (vii) combining the Re sulfide product with a Molybdenum (Mo) concentrate containing Re to obtain a Mo/Re concentrate; (viii) roasting the Mo/Re concentrate to obtain Mo oxide product and a flue gas containing Re; and (ix) treating the flue gas containing Re to obtain ammonium perrhennate. |
