Special Issue Information
Dear Colleagues,
High-purity quartz (HPQ), defined by SiO2 content >99.99% and ultra-low trace elements, is a critical enabler of advanced technologies. Its exceptional properties—including high transmittance, thermal stability, and electrical insulation—underpin semiconductor manufacturing, photovoltaic (PV) cells, fiber optics, and emerging applications in quantum computing and aerospace. However, in securing economically viable HPQ, dual challenges are faced: the scarcity of premium quartz deposits with favorable mineralogy and the complex, energy-intensive purification processes required to eliminate lattice-bound contaminants (e.g., Al, Li, and B).
The following Special Issue addresses the entire HPQ value chain, from geological formation and deposit characterization to innovative purification technologies (e.g., acid leaching, thermal chlorination, and flotation) and cutting-edge applications. We welcome research on trace element behavior, novel beneficiation methods, sustainable processing, and quality control. Contributions elucidating HPQ’s role in the energy transition and high-tech industries are particularly encouraged.

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.
