The recent research and development on mine drainage published in 2017 was summarized in this review. In particular, this review was focused on three main aspects: 1) mine drainage and its environmental impact, 2) prediction and prevention, and 3) treatment technologies. The first section covers physiochemical characterization, microbiological characterization, and environmental impacts. The second section includes mine drainage prediction and prevention. The final section focuses physiochemical treatment, biological treatment, passive treatment, and beneficial uses of mine drainage and treatment wastes.

“…OM is able for providing sites for the sorption of substance in the AMD. Previous research has shown that increasing pH and decreasing heavy metal concentrations in AMD with OM application (Arce et al, 2017;Idaszkin et al, 2017;Peiravi et al, 2017). In a study using a reactor applied with OM from grass litter, Lefticariu et al (2015) reported decreases in the concentration of SO4 (26-35%), Fe (36-62%), Al (78-83%), Mn (2-6%), Ni (64-81%), Zn (88-95%), Cu (72-85%), and Cd (90-92%) compared to the reactor without OM application.…”

Mining activity may potentially produce acid mine drainage (AMD), which has relatively high acidity and dissolved heavy metal concentrations. Constructed wetlands is one of the AMD management methods in which organic matter (OM) plays a very important function in reducing the concentration of heavy metals in AMD through absorption and precipitation processes. Three types of OM (empty fruit bunches of oil palm, chicken manure and water hyacinth) and five levels of OM (0, 10, 20, 30 and 40 Mg ha-1) were applied to reclaimed-mining soils (RMS) in an incubation study. A batch experiment was then performed to measure the effect of OM application on the maximum sorption capacity (Qmax) of iron (Fe) from the AMD onto the mixed soil-OM. The application of OM resulted in increases in soil pH, carboxylic groups, and total functional groups, in which these increases varied based on the types and amounts of OM application. This study also revealed that OM application resulted in increasing Fe sorption. The application of OM increased Qmax values from 2077 to 2348-3259 mg kg-1 (water hyacinth), to 2607-3635 mg kg-1 (chicken manure), and to 2219-2992 mg kg-1 (empty fruit bunches of oil palm). Increasing these Qmax values may ascribe to increasing functional groups of the RMS with OM application. The results prove the importance of OM in controlling the sorption of Fe from AMD onto soils.

“…Sulfated acid drainage constitutes an environmental problem which is frequently studied in mining waste derived from the exploitation of sulfides (Costa et al, 2008;Costa & Duarte, 2005;Delgado et al, 2019;Devasahayam, 2006;Idaszkin et al, 2017;Jennings et al, 2000;Lecomte et al, 2017;Lin, 1997;Ludwig et al, 2001;Nieto et al, 2013;Nieva et al, 2016Nieva et al, , 2018Nordstrom, 1982;Pons, 1973). In this type of environmental liabilities, sulfides are oxidized to sulfates generating an acid drainage that affects the soil and release large amounts of sulfates and heavy metals into the water (Bigham & Nordstrom, 2000;Ferreira et al, 2020;Konner, 1993;Lin, 1997;Lin & Quvarfort, 1996;Lövgren et al, 1990;Schwertmann & Fitzpatrick, 1993;Turner & Kramer, 1992;Yang et al, 2009).…”

Environmental liabilities have become one of the most important problems at environmental level, especially those located in urban areas. Within the area of the Río de la Plata coastal plain, industrial waste abandoned by an ancient sulfuric acid industry in a sector of the petrochemical center constitutes an environmental liability composed mainly of fragments of native sulfur. The aim of this work is to evaluate, from laboratory tests, the generation of sulfate acid drainage in environmental liabilities associated with the ancient sulfuric acid industry in order to identify the waste spatial distribution and to determine the impacts that they impart on the quality of the soil and groundwater. The results obtained show that the native sulfur scattered in the environmental liability associated with the ancient sulfuric acid industry constitutes a potential source of sulfated acid drainage that locally affects the soil, groundwater, and underground structures of the industrial center, and also small adjacent ecosystems. The interaction between native sulfur and the rainwater causes the oxidation of the native sulfur releasing protons and sulfates, which reach the groundwater through the infiltration water process, generating the acidification of the environment. The results provide useful draft for the management of environmental liabilities, and also the monitoring data obtained could assist in prioritization of remediation options, which constitute a problem of relevance and whose regulations for management and mitigation are still a controversial issue.
