| Abstract: |
| The crush, grind, homogenization, sampling of spent auto-catalysts and analysis of platinum group metals(PGMs) is the basis of all researches works. The main factor of influence the PGMs leaching recovery is its state and wrapped up by cerium-zirconium-aluminium melting. The various pretreating methods, for example, roast at low temperature, reduction, roast-reduction, roast in microwave, chlorinating roast, roast in sulphuric acid, roast in soda and alkaline pressure leaching, have been reviewed, the advantages and disadvantages of these methods are analyzed and compared, and hope to give helps to all researches of this field. |
