Separation of heavy metals from municipal solid waste incineration fly ash: A review

Ecotoxicology and Environmental Safety
More than 10 million tons of municipal solid waste incineration (MSWI) is discharged annually on the planet, which endangers ecosystem. Separation of heavy metals is a promising method for disposal of MSWI fly ash, which has been studied for decades ...

Scalable Direct Recycling of NMC532 From End‐of‐Life Batteries via Physical Separation and Solid‐State Relithiation

Advanced Energy and Sustainability Research, Volume 7, Issue 4, April 2026.
A scalable recycling method is presented for recovering high‐purity NMC532 cathode material from shredded end‐of‐life batteries using electrostatic, magnetic and size separation processes. This method produces a high‐purity cathodic black mass that, after heat treatment with recovered lithium salt, restores electrochemical performance and maintains ...

Study of the Effects of Multiple Organic Additives on Zinc Deposition During Zinc Electrolysis

Electroanalysis, Volume 38, Issue 4, April 2026.
The effects of different concentrations of ionic liquid additive 1‐ethyl‐3‐methylimidazole‐methanesulfonic salt [EMIM]MSO3 and glue on the cathodic potential and quality of zinc electrodeposition have been investigated. It was found that after 5 h of electrolysis and 1 h of potential decay, the corrosion rates of the Pb–Ag alloy anodes were 3.93, 3.77,

Advances in Hydrometallurgy [PDF]

, 2020
The development of new technologies and the increasing demand for mineral resources from emerging countries are responsible for significant tensions in the pricing of non-ferrous metals. Some metals have become strategic and critical because they are used in many technological applications such as flat panel TVs (indium), solar panel cells (indium ...

The effects of leaching from alkaline red mud on soil biota: modelling the conditions after the Hungarian red mud disaster [PDF]

, 2013
A soil column experiment was set up to investigate the effect of red mud from Ajka (Hungary) on a typical soil profile from the concerned area. The chemical changes caused by the leachate of the red mud and the effects of these changes on living ...

Direct Recycling of Mixed‐Oxide Cathodes: Balancing Cost, Performance and Environmental Trade‐Offs

Advanced Science, Volume 13, Issue 17, 23 March 2026.
Direct regeneration routes for mixed‐oxide lithium‐ion battery cathodes are systematically compared using harmonized techno‐economic, electrochemical, and environmental metrics. Solid‐state, hydrothermal, molten salt, electrochemical, and chemical relithiation methods are benchmarked to identify performance, cost, and sustainability trade‐offs.

Behavior and Study of the Kinetics Aspects of Hydrothermal Leaching Conducted on Thermal Activated Products of Complex Polymetallic Secondary Sulfide Concentrate [PDF]

Archives of Metallurgy and Materials
The utilization of complex polymetallic secondary sulfide concentrate (CPSSC) is difficult, owing to its special structure and composition. In this paper, CPSSC was firstly activated by roasting under atmosphere, followed by hydrothermal leaching under ...
