Extraction, Separation, and Recovery of Rare Earth Elements

Dear Colleagues,

Rare earth elements (REEs) are critical materials in modern technologies, ranging from electronics and renewable energy systems to advanced medical applications. Efficient extraction, separation, and recovery of REEs from primary ores, secondary resources, and industrial waste streams have become increasingly important due to their limited supply and growing demand. This Special Issue focuses on innovative strategies and technologies for the entire value chain of REE processing, including solvent extraction, ion exchange, precipitation, leaching, and emerging green and sustainable approaches. Contributions that advance the understanding of separation mechanisms, improve selectivity and efficiency, reduce environmental impact, or integrate computational and experimental methods are particularly welcome. By bringing together cutting-edge research on extraction, separation, and recovery, this issue aims to provide a comprehensive platform for scientists and engineers to address the technical challenges and explore sustainable solutions in the field of rare earth elements.

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. Separations 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 2600 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.
