Pehkonen COBALT RECOVERY FROM SPENT PORTABLE LITHIUM ACCUMULATORS AFTER THERMAL TREATMENT Abstract The possibilities of cobalt recovery from spent portable lithium accumulators were studied in this work. Incineration at 300, 500 and 700°C was realized in order to remove organic compounds. The highest loss on weight (around 25%) after incineration at 700°C was observed. Material after incineration was leached in 2M H2SO4 at 80°C without and with addition of H2O2. Leaching of treated samples with addition of H2O2 led to 100% of cobalt extraction. Thermal treatment of samples caused higher cobalt extraction at leaching without H2O2 addition in comparison to untreated samples. In general, positive effect of incineration on cobalt extraction was observed.
