Special Issue Information

Dear Colleagues,

According to a UN report, approximately 50 million tons of electronic waste containing multibillion dollars’ worth of metals were discarded around the world in 2018. The recovery of gold, copper, and other high-technology and critical metals from electronic waste is not only more environmentally friendly than extracting these metals using classical mining activities, but can also be more cost-effective. Urban mining aimed at metal extraction from electronic as well as other municipal and industrial solid waste streams promises to play an increasingly important role in maintaining market equilibrium and ensuring the sustainability of the different metal industries. This will lead to a positive impact on waste disposal globally as the circular economy comes to displace linear economics.

We invite contributions to this Special Issue on aspects covering recent advances in “Urban Mining and Waste Valorization”, which will be of direct interest to researchers and practitioners in the waste-processing field. Contributions reporting on material flow, sorting, dismantling, physical separation and treatment, hydrometallurgical and/or pyrometallurgical process development, extraction chemistry, and novel reagents are especially 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 papers will be 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 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.
