| Abstract: | According to the constituent characteristics of Li-ion secondary battery anode wastes,a recovery process for cobalt was studied.This process includes washing by organic solvents,acid dissolution,hydrolyzation,precipitatation and acid neutralization.Through the process,the CoSO4·7H2O was obtained,which conformed to the standard of chemical pure gradeHG/T2631-94].The recovery of cobalt exceeds 98%.Aluminum was recovered as metal. |
