Obtaining Nickel and Cobalt from Spent NiMH Batteries
Popis výsledku v původním jazyce
Nickel metal hydride (NiMH) batteries represent a great metal value. Their recycling is therefore important not only for environmental, but also for economic reasons. NiMH batteries used in this study were provided by a Czech company, which is responsible for collecting this type of wastes in the Czech Republic. The batteries were processed in a cutting mill. From the resulting material, the fraction <0.5 mm was obtained by sieving. Electrode mass of NiMH batteries was treated hydrometallurgically in order to obtain metal values. A mixture of electrode mass originating from different types of batteries contained 51.0 % Ni, 5.9 % Co, 1.1 % Zn, 0.7 % Fe, 2.18 % Mn, 9.2 % La, 4.6 % Ce, 0.7 % Pr and 2.3 % Nd. Leaching of the electrode mass was performed in1 and 2 mol/L H2SO4 at liquid-to-solid ratios 10:1 or 20:1 and laboratory temperature as well as at 60 and 80 oC. Extractions of 91.5 % Ni, 92.6 % Co and more than 97.5 % rare earth metals (RE) were achieved. More than 99 % RE were remov
