[en] Acidophilic bioleaching of black mass from shredded Li-ion batteries (LiBs) was performed
using a single strain and a consortium of 3 different ones. Thermal pre-treatment of the material has proved to be favorable in enhancing the bio-leachability of the contained metals. A single stage leaching allowed to recover approximately 70 % Co and 80 % Ni in 48 hours at 1 % pulp density. Jarosite formation plays a negative effect by blocking metal surfaces. SEM-EDS observations of input and leached material help to explain process-relevant peculiarities.
