Treatment, Beneficiation, and Valorization of Acid Mine Drainage

Dear Colleagues,

Contamination of different spheres of the environment with acid mine drainage (AMD) has been a worrisome issue of concern to national, regional, and international scientific communities alike. This is attributed to the magnitude of toxicological effects to living organisms upon exposure to AMD. Specifically, AMD grossly results from various geogenic and anthropogenic activities that lead to the generation of metalliferous and acidic drainage. In most countries, the mining of coal and gold are the benefactors to the generation of pollutant/toxicant-laden drainages. Due to various teratogenic, mutagenic, and carcinogenic effects posed by chemical species therein, regulatory frameworks require AMD to be treated prior to its discharge into various receiving compartments of the environment. This has resulted in the development of a wide array of technologies to treat, beneficiate, and valorize AMD. The quest for viable technologies is still ongoing, and recent initiatives are striving for zero-liquid-discharge (ZLD) processes in an attempt to foster the concept of circular economy and curtail ecological footprints of AMD.

This Special Issue welcomes papers proposing pragmatic, prudent, and eco-friendly solutions that promote treatment, beneficiation, and valorization of AMD. Papers presenting employment of innovative approaches at laboratory scales, field trials, pilot scales, and demonstrations are especially 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 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. 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 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.
