Dear Colleagues,

Mineral Biotechnology has been playing a new frontier on minerals processing, particularly in flotation science. Many mineral research centres, chemical industries, and academia are looking for new biochemical mixtures for a greener way to promote selectivity between minerals during flotation. The so-called bioreagents and their metabolic products/biosurfactants have been well thought out as new blends of environmentally friendly reagents for flotation. They can act as collectors, depressors, frothers, and flocculants.

On the other hand, electroflotation is a unit operation which is able to produce very tiny bubbles; one can choose the cell design, the kind of electrodes, and the proper solution chemistry to enable the flotation of fine particles.

This Special Issue will give attention to recent advances in mineral biotechnology and electroflotation. Papers on topics relevant to mineral particles bioflotation, including characterization of bacteria and their EPS, biosurfactants, and their role in flotation, will be mostly welcome. Moreover, subjects related to electroflotation of fine particles will reveal new approaches to mineral flotation science. All subjects, without a shadow of a doubt, play a paramount edge for a sustainable and less impactful way to the environment.

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.
