Research on the Recovery Process of Valuable Metals from Battery Waste
After extracting lithium from waste lithium-ion battery cathode materials,the waste needs to be treated deeply to recover nickel,cobalt,and manganese.The experiment uses acid leaching process to treat waste,and uses sulfuric acid to leach nickel,cobalt,and manganese.The experimental results show that when the raw material mass is 50 g,the amount of sulfuric acid is 80 g,the amount of water added is 200 mL,the leaching time is 60 min,and the leaching temperature is 80℃,the acid leaching effect of nickel,cobalt,and manganese is good,the nickel leaching rate is 99.48%,the cobalt leaching rate is 99.43%,and the manganese leaching rate is 89.24%.The acid leaching process can be used to treat waste,achieve efficient leaching of nickel,cobalt,and manganese,and lay the foundation for the separation of nickel,cobalt,and manganese,with good application prospects.
