Special Issue Information

Dear Colleagues,

This Special Issue aims to gather high-impact original articles as well as insightful review articles on mine tailings, including new innovations and best practices. Mine tailings, i.e., common mixtures of finely ground mineral particles and water, have been reported as a potential source of health and environmental problems [1,2], and there are over 12,000 tailings dams around the world [3]. They have also been identified as potential future resources, and thus, they can be reprocessed to recover the remaining value due to the technical advancement of characterization and processing. One of the unique characteristics of tailings is the presence of colloidal/fine particles that have been seen as a challenge for characterization and processing [4–8]. This Special Issue welcomes not only colloidal/fine particle aspects of mine tailings but also new developments on mine tailings as well as any related characterization and processing methodologies that can enhance the reprocessing and/or reduction of tailings. The keywords can be found below.

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. ChemEngineering is an international peer-reviewed open access semimonthly 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 1500 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.
