Special Issue Information
Dear Colleagues,
Bauxite is the main ore of alumina used to produce aluminum, and it is employed in diverse industrial applications depending on its grade. Bauxite’s grades are controlled by its chemistry, mineralogy, textural and structural aspects, and at least three main types of bauxite are known: lateritic, karstic and Tikhvin. The geochemistry of bauxites is also important as it can aid in the prediction of environmental issues related to mining. Therefore, bauxite's geochemical and mineral composition are critical for understanding its economic significance, guiding industrial processes, evaluating its environmental impact, and elucidating past geological processes.
This Special Issue welcomes the submission of articles that highlight innovative scientific approaches to the characterization of bauxite and that present discussions of its mineralogical, geochemical, textural and structural properties; this is in order to enhance the efficiency of bauxite processing and refinement, as well as encourage the application of sustainable and novel practices for bauxite recovery and the re-utilization of bauxite residues. Finally, the potential industrial applications of bauxite and its residues beyond alumina and aluminum production will be explored, including applications in the cement, chemical and refractory industry.
This Special Issue aims to foster a comprehensive understanding of the chemical and mineralogical composition of different types of bauxite, promoting further research regarding its industrial use while addressing environmental considerations related to its extraction and processing.

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.
