Abstract： Taking intoaccount thecost of recycling and the feasibilityofthe process，the experimentadopts aroasting acid leaching processto treat palldium/resin catalysts，aiming to effciently recoverpalladium elements from materials. Under the optimal process conditions，the roasting temperature is 600‰ ，roasting time is 5 h，leaching acidity is 4 mol/L， temperature is 80 C ， oxidant dosage is 3% of the raw material， leaching time is 2.5h ，liquid-solid ratio is 5，and the palladium leaching rate can reach 97.4% . The experimental results indicate that the roasting acid leaching process can be used to treat the material and achieve eficient leaching of palladium in the material， with good application prospects.
