REE Recovery from Mine Tailings & Effluents and Mineral Industrial Residue in the Context of Waste Management

Dear Colleagues,

Rare earth elements (REEs) have played a key role in our modern life. Due to their unique physical and chemical proprieties, REEs have been extensively used in various industrial applications such as modern electronics, green energy (wind power), transportation (hybrid and electric automobiles) and military applications. To keep up with the globally growing demand in a context where REEs extraction is becoming increasingly more stringent, due to the primary resource's scarcity and high extraction costs, the industry is increasingly turning to the recycling of different end-of-life products, mining and industrial residues.

Besides, the huge quantity of mining and urban mining wastes generated through all steps of mineral exploitation; mineral industrial production as well as at the end-of-life (EOL) of some products like permanent magnets and electronic and electrical equipment (EEE), require suitable management not to be a source of environmental pollution while they could be a promising potential as REEs sources. In light of this, new ideas to develop more advanced REEs recovery technologies from mine tailings and effluents, mineral industrial residues and EOL products are required to mitigate and minimize wastes management activities.

This Special Issue aims to collect a range of articles on different aspects of REEs recovery as secondary sources. The goal is to decipher all new technology and basic processes in REEs production. We hope this open-access Special Issue will provide a great opportunity to discuss the work of researchers working in this field around the world. Articles in all areas of hydrometallurgy, biohydrometallurgy, extractive metallurgy, and effluent treatment are highly 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).
