Mine water is one of the factors threatening the environment. The aim of the review article is to discuss and critically evaluate individual strategies for the remediation of neutral mine water. A critical evaluation is an essential tool to determine an appropriate remediation strategy. A wetland system is the preferred method of metal removal. However, the disadvantage is that it takes up more space compared to other methods and has a lower metal removal efficiency compared to active metal removal methods. When creating a suitable strategy, it is also necessary to assess the conditions of the mining site, which partially or completely prevent the use of the selected remediation strategy. The benefit of this review article is the processing of suitable combinations of treatment methods for the removal of potentially hazardous elements and their subsequent recovery. Future research in the field needs to focus on the analysis of the negative aspects of the environment that may disrupt or support the implementation of the selected method of remediation.

“…The performance of a cascade aerator in a passive treatment system for Fe(II) oxidation was assessed experimentally for net alkaline ferruginous mine drainage (Oh et al, 2015). The overall goal was to increase efficiency and reduce the size of the passive treatment system using an air diffuser cascade aerator.…”

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.

In predicting the acid-forming potential of rock samples, a combination of acid-base accounting (ABA) and net acid generation (NAG) tests has been commonly used. While simple and economical, this method sometimes shows low reliability such as categorizing certain samples as uncertain (UC). ABA and NAG tests were modified to selectively recover valid minerals in nature and substituted for the original tests. ABA test overestimated acid-producing capacity (in the case of weathered samples) and acid-neutralizing capacity (in the case of plagioclase-including samples) compared to the modified ABA test. NAG test yielded lower NAG pH compared to modified NAG test for samples with high total C content and low total S content. By comparing the correlation coefficients between acid generation amounts by the two evaluation methods, it was confirmed that modified evaluation method (MEM) has a much higher reliability (R = 0.9582) than existing evaluation method (EEM) (R = 0.5873). It was also concluded that exploiting advantages of both EEM and MEM is recommended where EEM is initially applied for general classification and a supplemented static test of MEM is executed for the purpose of correcting the error of UC categorized samples.
