The objectives were to beneficiate the magnetic sludge waste, PGM and Cu/Mo flotation tailings, in this work was to upgrade PGM and Cu-Mo to return to flotation process for further recovery or upgrading to the refinery. The results indicate that main conditions and processes of separations could be concentrated to Pt approximately 50~60 times from PGM flotation tailings by magnetic separation, 30~60 times to Cu and Mo from tailings by flotation, respectively. The physical separation and chemical / hydrometallurgical technology to concentrate and recover valuable metals lost in these waste to acceptable grades for subsequent are used and concluded as additional resource in respective industries.
