Special Issue Information
Dear Colleagues
About 20 years ago, mechanochemistry made its debut in the field of mineral processing. Since then, several high-intensity grinding methods were developed to enhance the extraction of metals from refractory minerals and ores. The large amount of energy exchanged in the mill chamber was proven effective at inducing not only physical but also chemical modifications in the minerals. Although the phenomena responsible for these chemical modifications are simply referred as “mechanochemical reaction”, their nature is complex, as it can go from simple lattice distortions to real conversion reactions. Now that processing refractory minerals and recycling has become crucial, investigating the mechanochemical activation and its mechanisms represents a matter of scientific and technological relevance.
This Special Issue aims to publish papers describing the mechanochemical effect associated with the use of high-intensity grinding methods. Works addressing the following topics will be given the highest consideration: (i) the isolation and assessment of the phenomena contributing to the mechanochemical activation and/or reaction of ores/minerals; (ii) the applicability of mechanochemical reactions to fields other than mineral processing (e.g., recycling, environmental remediation); (iii) the simulation and optimization of grinding operations, as well as the development of grinding systems to induce mechanochemical reactions in minerals.

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.
