“…The mobility of arsenic in mildly alkaline drainage from an orogenic lode gold deposit in the Bralorne mine, British Columbia, was studied by continuous monitoring of fourteen months on a quasi-weekly basis (Desbarats et al, 2015). The As self-mitigating capacity of drainage from orogenic lode gold deposits was found to be poor in high-pH and Fe-limited settings.…”

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.

Mine drainage from the mining of mineral resources (coal, metals, oil sand, or industrial minerals) remains as a persistent environmental problem. This review summarizes the scientific literature published in 2014 on the technical issues related to mine drainage or mine water in active and abandoned coal/hard rock mining sites or waste spoil piles. Also included in this review is the water from oil sand operations. This review is divided into the four sections: 1) mine drainage characterization, 2) prediction and environmental impact, 3) treatment technologies, 4) oil sand water. Many papers presented in this review address more than one aspect and different sections should not be regarded as being mutuallyexclusive or all-inclusive.

“…Their release into aquatic and terrestrial environments is a potential threat to environmental and human health. Being toxic and carcinogenic, arsenic release via acid mine drainage (Desbarats et al, 2015;Basu and Schreiber, 2013) and the elevated concentrations in waters, soils, and sediments are of particular concern.…”

Mining-contaminated waters may contain high levels of arsenic (As) and iron (Fe), among various metals and metalloids. The complex behavior of As makes its contamination difficult to remediate. This study aimed to determine the sources, possible association of As and Fe with colloids and their speciation and mobility in the Jiehe River, a stream impacted by gold mining. Particulate (>450 nm), colloidal (7 e450 nm), and truely dissolved (<7 nm) forms of As and Fe were determined, and the species of As [As(III), As(V), monomethylarsonic acid, and dimethylarsinic acid] and Fe [Fe(II) and Fe(III)] were both analyzed and modelled using geochemical program Visual MinteQ 3.0. High concentrations of As and Fe were observed in both filtered and particulate forms in most of the water samples. Total As was in the range of 1.0e719 mg L À1 with a median of 140 mg L À1. Total Fe was 0.4e68.2 mg L À1 with a median of 15.0 mg L À1. Arsenic was mainly adsorbed on ferrihydrite, goethite, and hematite in the upstream water samples. In contrast, it was mostly in truely dissolved forms in the water samples at downstream. Visual MinteQ 3.0 modelling results revealed that As adsorbed on, or co-precipitated with, stream sediment can be easily released under the environmental conditions of the downstream reach (11.4e37.5 km). These findings would benefit the environmental management of gold mining impacted Jiehe River, and indicate the need for further quantitative research on As migration facilitated by Fe (hydr)oxide colloids and the release of As from contaminated stream sediments.
