Direct recycling of Li‐ion batteries from cell to pack level: Challenges and prospects on technology, scalability, sustainability, and economics

Carbon Energy, Volume 6, Issue 6, June 2024.
Direct recycling methods can repair and regenerate battery constituents without destroying the materials down to the ionic or molecular level, unlike conventional hydro/pyrometallurgy. This comprehensive review walks through the direct recycling steps from big pack modules down to the material level, describing the state‐of‐the‐art advancements and ...

Copper leaching from waste electric cables by biohydrometallurgy [PDF]

Minerals Engineering, 2015
Abstract This study examines the leaching of copper from waste electric cables by chemical leaching and leaching catalysed by Acidithiobacillus ferrooxidans in terms of leaching kinetics and reagents consumption. Operational parameters such as the nature of the oxidant (Fe 3+ , O 2 ), the initial ferric iron concentration (0–10 g/L) and the ...

Electrochemical and structural characterization of recombinant respiratory proteins of the acidophilic iron oxidizer Ferrovum sp. PN-J47-F6 suggests adaptations to the acidic pH at protein level

Frontiers in Microbiology
The tendency of the periplasmic redox proteins in acidophiles to have more positive redox potentials (Em) than their homologous counterparts in neutrophiles suggests an adaptation to acidic pH at protein level, since thermodynamics of electron transfer ...

Biohydrometallurgy in the recovery of metal values.

Industrial Data, 2001
In current times, and with regard to extractive metallurgy, the use of new technologies for the recovery os values that can be present in minerals or in their concentrates and which can be hardly extracted by means of conventional technologies are shown special interest. One of these new technologies is bacterial leaching.
