Special Issue Information
Dear Colleagues,
There has been an increasing push toward recovery of metals from primary and secondary resources. Solvent extraction (SX), known as liquid–liquid extraction, is widely used to separate and concentrate metallic ions from aqueous solution in a broad field of industries, such as ore processing, agriculture, pharmaceuticals, petrochemicals, food industry, and industrial chemicals. Due to the growing demand for higher purity metals and the necessity to process low-grade ores with great complexity using environmentally friendly processing routes, SX is a well-established technique employed in hydrometallurgical processing of many metals such as Zn, Cu, Ni, Co, Fe, Cr, and rare earth metals. The simplicity, speed, selectivity, cost-effective and wide scope make SX the favored separation technique for metal recovery from aqueous waste streams. Nowadays, there is a large number of available extractants to selectively extract the desired metals, leaving other constituents in the aqueous raffinate, including acidic, basic and solvating. Ionic liquids also provide new prospects to process low-grade metal ores and to recycle metal ions. In addition, some modern and rapid methods have emerged to reduce solvent, time and energy consumption for maximizing the metal recovery, such as microwave and ultrasound treatment and synergic extraction.
This Special Issue is focused on solvent extraction of a particular metal ion or group of ions from various leach solutions or industrial waste waters, leaving behind the unwanted ions. Reviews and original articles in the areas of SX principle, extractant selection, extraction process optimization, as well as industrial applications, are welcomed.

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. Metals 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 2600 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.
