Metal oxide dissolution is central to most metal processing and is generally carried out using mineral acids. An alternative approach has been demonstrated for metal sulfides using electrochemical oxidation. Here the so-called paint casting method was employed to investigate the electrochemical dissolution and recovery of selected metal oxides. Cyclic voltammetry showed that all of the metal oxides were electrochemically active in deep eutectic solvent media, and the majority displayed a redox…

A Unified Method for the Recovery of Metals from Chalcogenides
Metal chalcogenides are ubiquitous starting materials for the extraction of metals from both primary and secondary sources. In this study, it is shown that chalcogenide compounds are electrochemica...
New hydrophobic DES based on tri–n-octylphosphine oxide and dicarboxylic acids: synthesis, spectroscopy and liquid–liquid extraction of actinides
A search is initiated for new solvents for liquid–liquid extraction (LLE) chemistry of actinides for future separations. Of late, reports on deep eutectic solvents (DES), which resemble ionic

The effect of pH and hydrogen bond donor on the dissolution of metal oxides in deep eutectic solvents
The dissolution behaviour of a series of d- and p-block metal oxides was investigated in deep eutectic solvents, DES, to determine the effect of pH and hydrogen bond donor (HBD) coordination strength
Electrodeposition of copper composites from deep eutectic solvents based on choline chloride.
This work pioneers the use of the electrochemical quartz crystal microbalance (EQCM) to monitor both current efficiency and the inclusion of inert particulates into the copper coatings and shows that progressive nucleation leads to a bright nano-structured deposit.
Direct electrochemical reduction of titanium dioxide to titanium in molten calcium chloride
An electrochemical method for the direct reduction of solid TiO2 is reported, in which the oxygen is ionized, dissolved in a molten salt and discharged at the anode, leaving pure titanium at the cathode.
Dissolution of pyrite and other Fe–S–As minerals using deep eutectic solvents
Processing sulfur containing minerals is one of the biggest sources of acute anthropogenic pollution particularly in the form of acid mine drainage. This study attempts to show an innovative method
Leaching and Selective Extraction of Indium and Tin from Zinc Flue Dust Using an Oxalic Acid-Based Deep Eutectic Solvent
Deep eutectic solvents have previously been used as cost-effective and readily available alternatives to conventional ionic liquids. Due to their versatile complexation properties, they are potential
EXAFS study into the speciation of metal salts dissolved in ionic liquids and deep eutectic solvents.
One of the main findings of this study is that, with respect to metal speciation, there is no fundamental difference between deep eutectic solvents and classic ionic liquids.
Voltammetric and spectroscopic study of ferrocene and hexacyanoferrate and the suitability of their redox couples as internal standards in ionic liquids.
It was found that neither ferrocene nor hexacyanoferrate are universally suitable as redox standards in the liquids investigated, Nevertheless, hexacynoferrate exhibits clear advantages in most of the strongly coordinating ionic liquids studied here.
