Flotation Reagents, Volume II

“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,

By increasing the complexity of ores, growing demand for mineral products, rising regulatory oversight, and the need to improve mineral separation processes, significant investigations for developing novel chemicals that can be used for mining applications are critical to have successful advancements in mineral beneficiation systems. Mineral separation by froth flotation involves types of chemical reagents. Reagents (surfactants) are mainly used for the surface modification of minerals and/or improve operating conditions for increasing the flotation separation efficiency. Reagents that can also impact the pulp chemistry make flotation a complex system involving all additives' interaction (including collectors, depressants, activators, pH regulators, and frothers). The flotation reagents may remain on the products (slurry, tail, and concentrate) and lead to different environmental problems or impact downstream processes such as pelletizing and bioleaching. Therefore, fundamental knowledge of chemical reagents, the principles of their reactions, the development of their new types, their applications for different ores, adsorption mechanisms, 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.
