Special Issue Information

Dear Colleagues,

The term bentonite is used for clayey material mainly composed of smectite group minerals—usually montmorillonite, saponite, nontronite, hectorite, and beidellite. Bentonites are broadly distributed around the world, with mine production led by China, the USA, Turkey, Greece, and India. Bentonites are mainly formed from the alteration of pyroclastic and/or volcaniclastic rocks. Clays like bentonite and clay minerals are studied and characterized by a variety of methods and techniques, including X-ray diffraction, infrared and MAS NMR spectroscopies in-situ synchrotron powder X-ray diffraction analysis, atomic force microscopy, scanning electron microscopy, and transmission electron microscopy.

In order to improve its properties, bentonite is in some cases modified by various techniques, e.g., thermal treatment, organoclay synthesis. Both raw and modified bentonite have a large number of uses and industrial applications. Some of these are: drilling muds, iron–ore pelletizing, waste water treatment, foundry sands, catalysis, agriculture, paper, cat litter, cosmetics, and pharmaceutical products. The suitability of bentonite depends on its physical, chemical, and mineralogical properties, such as smectite mineral content, presence of sulphates and/or sulphides, cation exchange capacity (CEC), hydrated radius of the interlayer cation, particle size distribution, and specific surface area (SSA). Different bentonite applications require a different set of properties, and therefore, their investigation is a rather demanding scientific area.

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 papers will be 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 1800 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.
