Proposed process for the simultaneous recovery of platinum-group (PGM) and Molybdenum (Mo) is totally evaluated. We calculate the mass balance of PGM, Mo, etc. based on the results of performance tests for each process, and evaluate the separation performance of PGM and Mo from HLLW and the reduction effect of the number of vitrified objects.
