Desorption and/or Reuse of Collectors in Mineral Flotation

Dear Colleagues,

Flotation is the most important method for processing mineral resources. In the flotation process, one part of the collector is adsorbed on the surface of the target mineral through physical/chemical interaction to make it float up into a concentrate, and the other part remains in the tailings pulp to form wastewater. The collector on the surface of the flotation concentrate will reduce the concentrate concentration/filtration efficiency and the hydrometallurgical leaching efficiency, increase the metal loss of the concentrate, and need to be removed and discarded before metallurgical operation. The collector in the tailings pulp will cause organic wastewater pollution, reducing the tailing settlement and wastewater recycling efficiency.

Therefore, this Special Issue will focus on the desorption and/or reuse of flotation collectors, including desorption and/or reuse methods, equipment, etc. The collector desorption and reuse on the surface of the concentrate will simplify the metallurgical process, improve the efficiency of concentrate hydrometallurgy, and reduce the cost of reagent in dressing plants. The simple treatment and reuse of the collector in the tailing pulp will reduce the cost of reagent and wastewater treatment in dressing plants and realize the recycling of wastewater. Relevant topics include but are not limited to the desorption and/or reuse of collectors in flotation of metal and non-metal minerals, the treatment and reuse of wastewater, solid–liquid separation, further treatment of flotation concentrate, etc. Original research papers, technical papers, and critical reviews featuring advances in the desorption and/or reuse of collectors are all welcome.

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.
