Special Issue "Hydrometallurgical Processing of Base Metal Sulphides"
Deadline for manuscript submissions: closed (29 February 2020).
Interests: nickel laterite processing; sulphides pressure oxidation; QXRD analysis; aluminosilicate processing; battery grade products
Base metals (and any associated PGMs and/or PMs) are generally recovered from sulphide concentrates in the initial stage using pyrometallurgical processing. However, as the grade and quality of sulphide resources continue to decline, it is becoming harder to generate feed materials that are suitable for smelting without incurring penalties. Apart from being employed for sulphide mattes, hydrometallurgical processes provide options for materials that are not amenable to smelting due to their low grade and/or impurity levels. Over the years, a vast range of these process technologies has been studied and, the technology has been commercially applied in a number of instances. The metal extraction step is typically characterized by approaches that range from pressure to atmospheric leaching in reactors, to leaching in vats or heaps (both chemical and biological) to in situ recovery.
This Special Issue invites contributions that examine hydrometallurgical processing technologies suitable for base metal sulphides and the various conventional steps from extraction to solution purification, metal concentration, and the recovery of the metal values. However, for some technologies, the focus instead is upon the removal of impurities and/or the enhancement of concentrate grade. Submissions on these subjects will enhance the expected diversity of this Special Issue. For the same reason, given that the processing of base metal sulphides may be required to enable the recovery of precious metals and/or platinum-group metals, relevant papers on these topics are also 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 1600 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.
