Topical Collection Information
Dear Colleagues,
Fine particle flotation presents persistent challenges due to its low collision efficiency, strong surface hydration, and high reagent consumption. These issues hinder the effective recovery of valuable minerals, especially as ore grades decline and fine-grained ores become more prevalent. Recent advances have focused on improving hydrodynamics through high-intensity flotation cells and micro/nanobubble technologies that enhance particle–bubble interactions. Innovations in reagent chemistry, such as selective collectors and polymer modifiers, have improved selectivity and attachment efficiency. Physical pre-treatments like desliming, ultrasound, and agglomeration flotation also show promise. Furthermore, computational tools like CFD-DEM and molecular dynamics offer new insights into microscale mechanisms, while machine learning assists in process optimization. Hybrid approaches—integrating flotation with other separation methods—are emerging as viable strategies. This collection highlights interdisciplinary solutions aimed at overcoming the intrinsic limitations of fine particle flotation, advancing both the science and practical applications of mineral beneficiation in complex ore systems.

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 collection 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.
