The importance of the flotation process to the economies of the entire industrial world is considered to be enormous. It is a gravity separation method, which is based on the idea of applying rising gas bubbles as the transport medium. Usually following the selective attachment of bubbles to particles, those solids are transferred from the body of water to the surface, where a foam is formed. Hence, as opposed to settling, flotation is a solid–liquid separation technique that is applied to particles of which the density is lower, or has been made lower, than the liquid they are in, by collectors and modifiers. Without flotation, many familiar metals and inorganic raw materials would be exceedingly scarce and costly, because the high-grade ores that could be processed by simple physical and mechanical methods have long since been used up. Thus, flotation initially originated from the field of mineral processing, usually termed “froth flotation”; a typical application is certainly with sulphide minerals. For many years, various particulate solids, in addition to minerals, have been extracted from water by using this effective process. These flotation applications mainly include the treatment of water and wastewater, as well as in paper recycling.

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 1400 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.
