Special Issue Information
Dear Colleagues,
The European Union’s (EU) list of critical raw materials is expanding. As of 2020, it contains 30 materials, including Rare Earth Elements (REEs), platinum group metals, while bauxite, lithium, titanium, and strontium have recently been added. REEs are important due to their usage in high-tech applications. The supply of critical raw materials is limited and is derived mostly from non-EU countries. The search for new REE deposits is in progress, as the most important global REE producer is China. As a result of the current metallurgical technology, some deposits whose REE budget is silicate minerals are not economical. The management of the elevated natural radioactivity associated with the REE-enriched minerals is also important. Apart from new leaching techniques of REEs from various sources, an overview of the current trends in the REE market is important in order to be able to define new strategies and encourage research that would make possible to exploit new deposits. A detailed study on the supply, demand, and in-depth analyses of the critical raw materials global market, including forecasts about the variation of the market trends, would encourage further research related to critical raw materials.
The purpose of this Special Issue is to provide not only new techniques about beneficiation of critical raw materials like REE leaching, but also analyses of the global market of critical raw materials, along with case studies of new critical raw material deposits that could be economical in the future due to the progress of metallurgical techniques and variations in the prices and global market.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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.
