Whereas other hydrometallurgical processes use strong acids, the ionic liquids are more benign and easier to handle. The liquids can be stripped of metals and re-used in a closed loop process. As part of the project, UK research organisation C-Tech set up a pilot plant, to process lithium ion and nickel-metal-hydride black mass.

Liquid aluminum settles on the bottom of the cell since it is denser (specific gravity 2.3 at 960 C) than the electrolyte (specific gravity 2.1). Periodically, this aluminum is siphoned off by vacuum

Gasification of spent pot lining from the aluminum

Mar 12, 2021 Abstract Aluminum production generates enormous spent pot lining (SPL) waste of around one million tons yearly, and these wastes are usually disposed in landfills. Hence, the technical feasibility of SPL gasification using both equilibrium and reactive high-fidelity modeling was evaluated in this study.
