Special Issue Information
Dear Colleagues,
Supergene minerals form when rocks or buried primary orebodies are exposed at or near the Earth’s surface and undergo oxidation, dissolution and reconcentration of elements. These interactions lead “immobile” elements to be concentrated and the released mobile cations to be recombined, forming supergene minerals. Supergene fluids change the distribution patterns of many elements, which diversifies the class mineralogy. It offers potential new mineral species to be discovered. The study of these minerals is important to reveal key information about earth-surface processes: element mobility, meteoric fluid–rock interactions, the oxidation-reduction process, landscape evolution and geodynamics, and critical roles of global climate regulation. They are also natural scavengers of toxic elements released in the environment and potential hosts of strategic and precious metals. Supergene ore-forming minerals have an economic importance at the first stage of mining activity: they increase the ore grade and ease the extraction process. However, they remain understudied because of their complex mineralogy and are often considered as obstacles to metal recovery. This Special Issue is dedicated to this mineral group with a special focus on their mineralogy and processes that lead to their formation.

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.
