| 简介 |
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; and filtering the Re precipitate from the metal salt solution to obtain a Re filtercake. The method further has the step of drying and formulating Re to produce Re sulfide product. |
