Special Issue Information
Dear Colleagues,
To meet the challenges of dwindling resources and the growth of needs, as well as in a perspective of a secure supply approach of high-tech metals, three options are considered based on the extraction of metals from primary and secondary resources (new deposits, mining and industrial wastes). Whatever the resource, metal extraction and purification is performed mainly by pyrometallurgy or hydrometallurgy that can sometimes coexist within one. The first type is the one that industry provides most of the elements as metal. However, this requires a large amount of energy and causes corrosion issues associated with high temperature operations in molten salts. The second process is the only one that currently allows efficient separation of metal targets, especially those contained in low grade polymetallic matrices. Understanding these challenges facing metals supply today requires consideration, not only of the sources (whether from mines or waste streams), but of the development of low cost, eco-friendly, secure and always more efficient processes.
This Special Issue aims to address research devoted to exploring the potentialities of solvent extraction to efficiently and selectively recover and purify metal targets from ores. Articles focusing on non-conventional separation techniques (ionic liquids, supercritical fluids…) are welcome here.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Minerals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
