New Insights into Mine Reclamation: Techniques for an Integrated Approach to Environmental Remediation

Dear Colleagues,

Mining is an essential activity that supports technological civilization. However, minimization of the associated impacts and subsequent restoration of mining areas is the biggest challenge facing the sector. Mine reclamation has previously focused on minimizing environmental impacts and preparing the land for productive uses during and after exploitation. Geomorphic changes are generally required to minimize erosion processes and leaching of metal(loid)s, even when the tailings and other waste generated are disposed of in mine dumps. In this respect, some (in)organic amendments and remediation technologies, such as stabilization, nanoremediation, and phytoremediation, are required to immobilize pollutants. Using vegetation to restore soils is in itself a complex process and may determine the potential economic value of degraded land. New phytoremediation techniques provide opportunities for a circular economy, supporting forest and agricultural yields to generate sustainable production options in rural areas. In this Special Issue, the role of different approaches will be considered, with special emphasis on a multifaceted approach to mine reclamation. Topics include but are not limited to the following:

• Stabilization of mine soils and waste by using amendments (compost, biochar, etc.);
• Nanoremediation for treatment of mine soils and wastewater;
• Forestry reclamation;
• Energy crops in mine soils/dumps;
• Agricultural opportunities regarding mine soils.

Authors are invited and welcome to submit original research papers, reviews, and short communications.

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. Environments 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.
