Special Issue Information
Dear Colleagues,
Physicochemical methods for recovering metals from primary and secondary raw materials play a significant role in modern metal production technologies. Hydrometallurgical methods for obtaining valuable metals constitute one of the fundamental methods for processing polymetallic raw materials. Leaching is the most important step in metal extraction. This process must be preceded by a series of preliminary operations. The rational selection of the appropriate leaching agent is dictated by the type, properties and chemical and mineralogical composition of the raw material. The possibility of the efficient and economical processing of leaching solutions is also important. Extractants used in hydrometallurgical processes to separate metal ions from aqueous solutions are organic compounds with highly diverse molecular structures and various physicochemical properties. The selection of an appropriate extractant is determined by factors such as the composition of the leaching solution, pH, and the concentration of accompanying metals. Extractants are almost never used in their pure form.
This Special Issue aims to explore cutting-edge solutions for the recovery of metals. At the same time, the issue will focus on the recycling of non-ferrous metals—an area of growing importance as we move towards a circular economy. Recycling not only helps to mitigate the environmental footprint of metal production but also plays a crucial role in resource conservation, contributing to the long-term sustainability of the industry.
Metals are essential for the advancement of high-tech applications, including renewable energy technologies and electric vehicles.
The production of modern materials requires critical, strategic metals, such as rare earth elements, lithium, cobalt and platinum group metals. This Special Issue seeks contributions that address the most important challenges in metals separation and refining technologies, from recycling strategies that reduce reliance on primary resources to the production of modern materials.

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. Applied Sciences is an international peer-reviewed open access semimonthly 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.
