Over the past three decades, there has been systematic growth in the application of bio- and hydrometallurgical methods. Depletion of the primary metal resources and stricter environmental regulations have triggered a need for the use of low-grade ores and waste. This Special Issue focuses on bioleaching as an alternative method of metal extraction from ores, concentrates, slags, and mine tailings involving microorganisms. In a natural environment, bacteria associated with minerals are also responsible for bio-weathering and biocorrosion. The result of all presented processes is acid mine drainage (AMD), which is a source of a wide variety of metal ions. Leachate generated from bio- and chemical processes is a metal-rich solution. There is still a need to propose systems and operations for selective recovery of metals from polymetallic solutions but also to develop other applications of this kind of solutions, e.g., in nanoparticle synthesis. Another critical issue is waste management.
Schwertmannite, jarosite, ferrihydrite, and goethite as secondary iron hydroxysulfates are formed in acidic and sulfate-rich environments. They affect the bioleaching process but can also serve as sorbents for toxic metals to prevent environmental pollution, e.g., via the immobilization of arsenic ions. Therefore, the role of secondary minerals in leaching and bioleaching processes is worth explaining.

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 1800 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.
