Applicable and Industrial Developments in Froth Flotation

Dear Colleagues,

Process engineers annually treat thousands of million tonnes of primary and secondary raw materials with conventional ore-dressing processes involving several back-to-back steps. Froth flotation is undoubtedly the key process that relies upon the physicochemical differences of mineral surface properties. However, after more than a century, various aspects of this complex separation technique have not been discovered yet. This Special Issue aims to highlight the recent industrial and applicable academic elaborations in the flotation of metallic and non-metallic minerals. The current Special Issue will mainly focus on key findings for the serious challenges that froth flotation currently faces, such as:

• Impact of the polymineralization of deposits, their characterization issues, and process mineralogies on separation performance;
• Optimization of operating properties via advanced, efficient, and cost-effective techniques;
• Novel perspectives in designing flotation circuits, machinery, and the minimization of energy usage;
• Developments in the practical treatments of extremely coarse and fine particles using conventional cells, flotation columns, and Jameson, Imhoflot^TM, flash, fluidized bed, HydroFloat^TM, oscillating grid, and Reflux flotation cells;
• Appropriate selection of typical and new chemical reagent regimes and assessment of their environmental impacts on downstream processes;
• Role of fresh and saline water properties in different stages of flotation systems, with a particular focus on solution chemistry;
• Applicability of practical and first-principle flotation kinetic models and their scale-up in industrial cells;
• Individual and coupled numerical modeling approaches and their applications to full-scale cells;
• Impact of pre-treatment and pre-concentration techniques on the floatability of precious and gangue minerals.

This Special Issue will compile innovative outcomes for research and technology developments in advanced mineral processing. We cordially invite scientists to share their achievements regarding advances in 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. J is an international peer-reviewed open access quarterly 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 1200 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.
