Froth Flotation

Dear Colleagues

Froth flotation has been the most important technological invention to provide humankind with the metals required. However, ores have become leaner and more complex to process, challenging our long-held technological solutions.

Requirements to reduce global warming by reducing CO₂ emissions bring considerable challenges to mineral beneficiation, especially the development of froth flotation technology. The challenges are both systemic and deposit related, and go from theoretical understanding to plant practices. Challenging themes include resource efficiency, energy, and water use. The future ores will be leaner and more complex to process. The solutions developed by the mineral processing community to address these issues will dictate the future of the field.

However, there are new and interesting insights into froth flotation, its operation and chemistry, and efforts to mitigate energy and water use, all of which merit publication.

Technical papers discussing new theoretical aspects of froth flotation, new reagents, and new operational innovations and processes for all types of ore deposits (including industrial minerals and secondary raw materials) are invited to this Special Issue on Froth Flotation.

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.
