Flotation Reagents

“Without reagents there would be no flotation, and without flotation the mining industry, as we know it today, would not exist.” Handbook of Flotation Reagents by Srdjan M. Bulatovic

Dear Colleagues,

Separation by froth flotation involves many types of reagents. Reagents are mainly used for treating the surface of ores and/or for improving conditions of operations for increasing flotation separation efficiency. Reagents can impact the pulp chemistry and make flotation a complex system involving the interaction of all additives (including collectors, depressants, activators, pH regulators, and frothers). The flotation reagents may remain on the products (slurry, tail, and concentrate) and lead to many environmental problems or have a great impact on downstream processes such as bioleaching. Therefore, fundamental knowledge of chemical reagents, the development of their new types, using them for different conditions, and minerals and surface chemistry studies in the presence of various reagents are typical and essential investigations in mineral processing.

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.
