Flotation Theory and Technology

Dear Colleagues,

Flotation, as a pivotal mineral separation technique, relies fundamentally on breakthroughs in its theoretical foundation and process innovations to enable the utilization of low-grade and complex mineral resources. The core of the flotation process hinges on the precise control of the physicochemical properties of mineral surfaces, achieving the efficient separation of target components through reagent–mineral–bubble interfacial interactions. In recent years, interfacial interaction mechanisms at the micro/nano scale, the efficient separation of low-grade/refractory ores, and green and intelligent transformation have emerged as central drivers advancing flotation technology. This Topical Collection focuses on groundbreaking progress in flotation fundamentals, novel flotation processes, the development of environmentally friendly flotation reagents, and intelligent mineral processing technologies. Original research papers encompassing flotation theory, processes, equipment, and interdisciplinary applications are solicited, with a particular interest in systematic innovations enabling the green development of low-grade mineral resources.

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 250 words) can be sent to the Editorial Office for assessment.

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.
