New Trends in Sustainable Extraction of Energy-Critical Minerals

Dear Colleagues,

The global transition to clean energy technologies has intensified the demand for energy-critical minerals, essential for renewable energy systems, energy storage, and advanced electronics. However, conventional extractive metallurgy and mineral processing methods are often energy-intensive, costly, and of environmental concern. These methods are generally not circular and, consequently, are unsustainable in the long term. This Special Issue, New Trends in Sustainable Extraction of Energy-Critical Minerals’, aims to highlight innovative approaches that enhance the efficiency, selectivity, and environmental performance of energy-critical mineral extraction and processing. Key topics include, but are not limited to, advancements in hydrometallurgy, novel ligands for solvent extraction and saponification, bio-based extraction techniques, ionic liquid and deep eutectic solvent applications, and electrochemical- and membrane-based separations. Additionally, this Special Issue will explore circular economy strategies, including recycling, urban mining, and closed-loop processing, as well as the role of machine learning and process modeling in optimizing extraction techniques. Contributions focusing on low-waste, low-carbon, and socially responsible extraction pathways are especially encouraged. By bringing together cutting-edge research from academia and industry, this Special Issue aims to accelerate the adoption of sustainable extraction methods that support the secure and responsible supply of energy-critical minerals. Researchers, engineers, and scientists are invited to contribute original studies and reviews that shape the future of sustainable extractive metallurgy.

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. Eng 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 1400 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.
