As a potential reusable resource, solid waste is gradually being used for extracting valuable
metals. In recent years, new technologies such as electrochemistry, supercritical fluids, ionic …

Rhenium is a scarce and highly important metal, which is widely used in high-temperature
superalloys and platinum–rhenium catalysts due to its unique physicochemical properties …

Hydrometallurgy is an efficient way of recovering metal ions from mineral ores where the
most important steps are the leaching of the minerals, the recovery and purification of metal …

This review addresses research and development on the use of ionic liquids as extractants
and diluents in the solvent extraction of metals. Primary attention is given to the efficiency …

Abstract Molybdenum (Mo) and rhenium (Re) are strategic key metals for the development of
modernization. In nature, 99 wt.% of Re is associated with molybdenite minerals via the form …

In this review, the performance of ionic liquids (ILs) as separating media for selective and
sustainable extraction of rare-earth elements (REEs) is analyzed. ILs as solvents have been …

Cobalt (Co) stands out as one of the most critical metals in contemporary use, particularly
due to its increasing demand in technological products and especially in electromobility …

A cold-induced-homogeneous liquid–liquid extraction method combined with deep eutectic
solvent-based dispersive liquid–liquid microextraction has been done to extract several …

The low mass transfer effect of dilute solution results in low recovery efficiency of critical
metal Re ions from ultralow-concentration metallurgical industrial effluents. Bubble driving …

The separation of rare earth (RE) and aluminum (Al) has always been a practical challenge.
In this article, a novel functionalized ionic liquid 1-butyl-3-(3, 3-dimethyl-2-oxobutyl)-imidazol …
