| Abstract: |
| Effects of ratio of soda to material with water mixing on recovery of PGMs, RE and aluminum from spent auto-catalyst by roasting with soda and water leaching process were investigated. PGMs are enriched 9.97 times and cerium recovery is 68% above after roasted with soda and leached with water. Content of Al and Si in water washing solution is 10 g/L above, which can be used to prepare polyaluminium sulfate flocculant. |
