“…In the Illinois Basin this has been a significant and costly problem as extensive mining was carried out during the last century (Behum et al, 2011). Concern over the impact to drinkingwater resources make remediation of coal-generated AMD imperative in many mining regions around the world (Cravotta, 2008;Baruah and Khare, 2010;Chen et al, 2015). However, remediation of these drainages to the point of meeting the surface water quality standards has proved challenging because of the extreme geochemical characteristics of certain coal-generated AMD (Behum et al, 2011).…”

“…The sediments in the Hengshi River, one of the tributaries of the Beijiang River near the Dabaoshan Mine in south China, have been heavily cocontaminated by several heavy metals (Chen et al ; Liao et al ). The sampling site selected is located just downstream of the waste pond of Dabaoshan Mine.…”

“…In river systems close to nonferrous metal mines and smelter factories, sediments act as major sinks for heavy metals in the aquatic environment (Wei and Yang ; Liao et al ; Mouni et al ). The Hengshi River, for example, one of the tributaries of the Beijiang River near the Dabaoshan Mine in south China, has been heavily contaminated by several heavy metals such as cadmium (Cd), copper (Cu), lead (Pb), manganese (Mn), and zinc (Zn; Chen et al ; Liao et al ). However, heavy metals are not permanently bound to the sediments and under changing environmental conditions, they can be resuspended and remobilized into the overlying water and become a secondary pollutant source.…”

The release of in situ heavy metals (cadmium [Cd], copper [Cu], lead [Pb], manganese [Mn], and zinc [Zn]) from contaminated river sediment near a Cu-iron mine in South China was experimentally studied. The effects of pH values and the kinetics of heavy metal release were investigated. In addition, species of the 5 metals in the sediment were determined as a function of pH and time. Rates and extents of metal desorption were studied over 30 d, and a 3-parameter, 2-compartment model was used to analyze the desorption kinetics. The rate constants (k s ) for the slowly desorbing fraction of heavy metals were found to be 5 to 6 orders of magnitude lower than the corresponding rate constants (k r ) for the rapidly desorbing fraction, suggesting that slow desorption is the rate-limiting step. The partition coefficients (K d ) varied significantly among metals, on the order Pb > Cu >Zn > Cd > Mn, indicating that the sediment had a much higher retention capability for strongly hydrolyzed metals than for weakly hydrolyzed ones. The amount of metals released from the sediment decreased dramatically at the final pH of 2 to 4 and leveled off in the pH range of 5 to 8. Release time and pH exhibited a varied influence on the fractionation of metals, and had a more remarkable influence on more mobile fractions and hardly any effect on the residual fraction during the desorption process. The fractionation of strongly adsorbing metals like Pb was not as dependent on release time and pH as it was for the weakly bonded metals like Mn and Cd. The results indicate that in situ heavy metals may exhibit a sustainable potential for release and may increase health risks when the pH of the river is lowered. Environ Toxicol Chem 2019;38:464-473.

“…Sulfate migration was investigated in an AMDaffected river in the Dabaoshan mine area of South China, with the goal of identifying an appropriate remediation strategy (Chen et al, 2015b). Geochemical model calculations indicated the river waters were supersaturated resulting in the potential for precipitation of iron oxyhydroxides.…”

This review provides a snapshot of papers published in 2015 relevant to the topic of mine drainage generation and control options. The review is broken into 3 sections: Generation, Prediction and Prevention, and Treatment Options. The first section, mine drainage generation, focuses on the characterization of mine drainage and the environmental impacts. As such, it is broken into three subsections focused on microbiological characterization, physiochemical characterization, and environmental impacts. The second section of the review is divided into two subsections focused on either the prediction or prevention of acid mine drainage. The final section focuses on treatment options for mine drainage and waste sludge. The third section contains subsections on passive treatment, biological treatment, physiochemical treatment, and a new subsection on beneficial uses for mine drainage and treatment wastes.
