“…The physical, geochemical and mineralogical properties of waste rock dumps are determined by the physical configuration, geochemical distribution, temperature and transport of air and water through the waste rock dump (Tran et al, 2003). The period of storage is an important factor determining the potential and viability of mine waste rocks to produce ARD as studies by (Abrosimova et al, 2015) indicated that 26% of rock samples produced acidic effluent following a long-term storage period in the laboratory.…”

Acid Rock Drainage (ARD) is a well-known problem related to the mining industry due to its hazardous environmental effects. Metal-rich drainage and acid effluent transmitted from mine waste dumps compromise environmental quality of groundwater and surface water systems destroying aquatic life and increasing human health risks. This study was aimed at assessing the acid and metal drainage potential from the Subriso East Rock Dump (SERD) located in the Wassa East district of Ghana on ground and surface water quality in the catchment using a system of monitoring boreholes, reference boreholes and river samples. Water samples were collected from deep and shallow monitoring boreholes and surface water within the immediate environs of the SERD

“…Of these, the most commonly occurring is the sulfide molybdenite. This occurs as a major component in mine wastes of Moand Cu-Mo porphyry deposits [33,45,46], epithermal Au and Au-Ag-(Te) deposits [32] and W-Mo porphyry-greisen deposits [47]. Molybdenite often occurs with other sulfide minerals, including pyrite and chalcopyrite (e.g., in sediments associated with waste-water effluents from the concentration plants of Sarcheshmeh Cu mine, SE Iran [31]).…”

“…Tugarinovite and molybdite were identified through X-ray diffraction (XRD) analysis by Abrosimova et al [45] in a waste rock sample containing several oxidized grains at the Ak-Sug porphyry Cu-Mo deposit, Russia. A Mo oxide with an MoO 3 composition typical of molybdite was also found in minor amounts (1.92% of the total Mo-bearing mineral composition, with the remaining 98.08% as Mo sulfide) in ultrafine tailings from an obsolete molybdenite reservoir in Zhejiang province, China [48].…”

Abstract:Molybdenum is an essential element for life, with growing production due to a constantly expanding variety of industrial applications. The potentially harmful effects of Mo on the environment, and on human and ecosystem health, require knowledge of Mo behavior in mining-affected environments. Mo is usually present in trace amounts in ore deposits, but mining exploitation can lead to wastes with very high Mo concentrations (up to 4000 mg/kg Mo for tailings), as well as soil, sediments and water contamination in surrounding areas. In mine wastes, molybdenum is liberated from sulfide mineral oxidation and can be sorbed onto secondary Fe(III)-minerals surfaces (jarosite, schwertmannite, ferrihydrite) at moderately acidic waters, or taken up in secondary minerals such as powellite and wulfenite at neutral to alkaline pH. To date, no Mo-metabolising bacteria have been isolated from mine wastes. However, laboratory and in-situ experiments in other types of contaminated land have suggested that several Mo-reducing and -oxidising bacteria may be involved in the cycling of Mo in and from mine wastes, with good potential for bioremediation. Overall, a general lack of data is highlighted, emphasizing the need for further research on the contamination, geochemistry, bio-availability and microbial cycling of Mo in mining-affected environments to improve environmental management and remediation actions.

“…The analysis combined high resolution inductively coupled plasma mass spectrometry (HR-ICP MS) for the evaluation of dissolved and particulate constituents, with diffusive gradients in thin films (DGT) supported by modelling approaches to determine element speciation (Omanovi et al, 2015). Russia (Abrosimova et al, 2015). In general, the waste rock materials had a low AMD potential with 26% of the rock samples producing acidic effluent following long-term storage.…”

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.
