Copper can be extracted from the main copper mineral, chalcopyrite, without the formation of hydrogen sulfide or sulfur dioxide. 
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...

Speciation of Copper(II)-Betaine Complexes as Starting Point for Electrochemical Copper Deposition from Ionic Liquids.
TLDR
For the first time, copper is deposited from the ionic liquid [Hbet][NTf2 ], giving promising opportunities for more resource-efficient copper plating.
Engineering a tandem leaching system for the highly selective recycling of valuable metals from spent Li-ion batteries
With the rapid development of lithium-ion batteries (LIBs), the selective recovery of lithium and other valuable metals from spent LIBs is in urgent need because of the shortage of Li and valuable
Electrochemical oxidation as alternative for dissolution of metal oxides in deep eutectic solvents
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
Integrated Leaching and Separation of Metals Using Mixtures of Organic Acids and Ionic Liquids
TLDR
The [P44414]Cl + CH3COOH system was applied to the treatment of real waste, NiMH battery black mass, being shown that it allows an efficient separation of Co(II) from Ni(II), Fe(III) and the lanthanides in a single leaching and separation step.

Ionic liquids for metal extraction from chalcopyrite: solid, liquid and gas phase studies.
TLDR
It is suggested that the CS2 produced upon leaching could be responsible for decreasing the sulfur, but not oxide, layer on the surface of chalcopyrite samples and therefore more efficient leaching.
