During the operation of a mine, and particularly post-closure, stored mine wastes, including waste rock, low-grade ore, tailings and any coarse-grained processing wastes, are susceptible to the climatic setting of the mine site. Seasonal rainfall infiltration and evapotranspiration from revegetated mine waste storages, plus access to oxygen, will dictate the water content of the mine wastes, their reactivity, and the quality of any seepage and runoff from the storages over time. The climate will also vary from year to year, and may vary over time due to climate change.
Coarse-grained mine wastes typically start out relatively dry, and have ready access to oxygen in dumps. Over time, the coarse wastes wet-up due to rainfall infiltration, at a rate dependent on the amount and intensity of rainfall, the particle size distribution of the wastes, and the height of the dump. When the water storage capacity of the dump is exceeded, seepage will emerge from the base and at low points around the toe of the dump. The seepage will carry with it any oxidation products and contaminants. The closure of the dump will generally involve constructing a cover to limit the net percolation of rainfall and/or oxygen ingress.
Mine tailings are typically deposited as a slurry, and may drain down and desiccate, allowing oxygen ingress. Tailings can produce seepage and runoff, which may be contaminated. The closure of the tailings facility will generally involve constructing a cover to limit the net percolation of rainfall and/or oxygen ingress, and requires that the tailings are trafficable.

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. Water is an international peer-reviewed open access semimonthly 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 2200 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.
