Special Issue Information

Dear Colleagues,

Recent history has seen unprecedented metal demand coupled with tightening legislation and societal expectations around sustainability. The challenge of meeting both simultaneously is driving a paradigm shift in metal production with a much greater impetus on utilizing waste streams from all sources to supplement metal production and provide positive environmental outcomes. While the focus may drive policy and company strategy change, an array of technological advancements is necessary to realize the ability to recycle and recover the metals economically and sustainably.

This Special Issue on “Advanced Methods of Metal Recycling” seeks high-quality works focusing on metal recovery processes from waste products and industrial streams. Topics include, but are not limited to, metal recovery from the following:

  • End-of-life products—consumer waste;
  • Infrastructure—construction metals, utility materials, solar panels, etc.;
  • Industrial waste—mining, processing, and manufacturing.

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. Processes 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.

This study presents the results of an investigation into the effectiveness of microwave (MW) treatment (1) as a preconditioning method for technogenic raw materials (2) to enhance zinc (3) leaching (4) efficiency. Selective dielectric heating facilitates phase transformations (5), converting sphalerite (ZnS) into zinc oxide (ZnO), which exhibits significantly improved acid leachability. The response surface methodology (RSM) was utilized to evaluate critical operational variables, encompassing sulfuric acid concentration, leaching period, slurry density, and thermal conditions. The obtained results confirm the potential of MW treatment in hydrometallurgical processes, offering a sustainable and energy-efficient alternative for processing technogenic raw materials.
