Process for recovering valuable metal from waste catalyst |
| abstract |
A process for recovering valuable metals from a waste catalyst based on an alumina carrier includes (a) roasting the waste catalyst at a temperature range of 400° to 1,000° C. to obtain a roasted product; (b) preparing a reduction dissolution by dissolving the roasted product with sulfuric acid in the presence of a metal as a dissolution catalyst; (c) separating a large part of the aluminum from the reduction dissolution solution and recovering aluminum as ammonium aluminum sulfate from the solution, optionally after subjecting the reduction dissolution solution to a treatment of removing iron; (d) extracting molybdenum as a molybdate by solvent extraction from the solution after separating and recovering aluminum from the solution; (e) extracting vanadium as a vanadate by solvent extraction from the solution obtained as a residue after extracting molybdenum; and (f) recovering nickel and cobalt each as a hydroxide from the extraction residue after recovering vanadium. |
