“…Several studies by Hällström et al (2018aHällström et al ( , b, 2020a) and Salifu et al (2018Salifu et al ( , 2019Salifu et al ( , 2020a at the Yxsjöberg mine site have shown that the complex interplay between compounds (SO 4 2− , CO 3 2− , and F − ) released from the weathering of sulfides, carbonates, and fluorite has generated a geochemical environment in which Be, Bi, and W are mobilized from their primary minerals within the Smaltjärnen tailings. The Smaltjärnen tailings are enriched in F (1.9 wt%) and S (1.2 wt%), together with the trace elements Be, Bi, Ga,Ge,and W (284,496,24,16,and 960 ppm,respectively), and have been stored open to the atmosphere for more than 50 years (Hällström et al 2018a, b).…”

There is a potential risk that the geochemical cycles of several critical metals will be affected when mining of these metals increases to meet the demand of green technology. The geochemistry of Be, Bi, Ga, Ge, and W, herewith called CM5, is lacking, yet is necessary to ensure responsible mine waste and water management. Beryllium, Bi, and W are all considered immobile, but in previous studies of skarn tailings in Yxsjöberg, Sweden, all three elements were mobilized. The tailings are enriched in CM5, together with pyrrhotite, calcite, and fluorite. The mobility and environmental impact of CM5 and F in surface waters downstream of the Yxsjöberg mine site, Sweden, were studied using monthly water samples from seven locations and analysis of diatoms at five of these locations. Bismuth, Ge, and W were present at low concentrations, transported in the particulate phase, and likely settled in the sediments hundreds of meters from the tailings. Beryllium and F were present at high concentrations and dominantly transported in the dissolved phase. At these pH conditions (5.6), Be should form insoluble hydroxides; however, elevated concentrations of dissolved Be were observed more than 5 km from the mine site. Diatoms downstream of the mine site were negatively affected by the mine drainage. The release of low quality neutral mine drainage will continue for hundreds of years if remediation actions are not undertaken since only a small portion of the tailings have weathered during 50–100 years of storage.

“…Over the last decade, studies of the impact of mining on the surrounding groundwater environment have been vigorously pursued worldwide, with examples being the impact of AMD generated in coal mines on karst groundwater [24,25], estimation of natural and mining impacted contributions to instream metals [26,27], and the evaluation of AMD attenuation using stable-isotope ratios of metals as tracers [28]. Case studies have also been reported, including on the calculation of mixing ratios of AMD and surface water based on stable-isotope ratios [29], chemical transfer processes in waste-rock piles [30,31], and conceptualization of underground flooded mine reservoirs and groundwater flow modeling [32]. On the other hand, metal mines in Japan were mainly underground mines, and some mines still have drainage tunnels accessible to the public.…”

Acid Mine Drainage Sources and Impact on Groundwater at the Osarizawa Mine, Japan

et al. 2021

Understanding the origin of acid mine drainage (AMD) in a closed mine and groundwater flow system around the mine aids in developing strategies for environmental protection and management. AMD has been continuously collected and neutralized at Osarizawa Mine, Akita Prefecture, Japan, since the mine was closed in the 1970s, to protect surrounding river water and groundwater quality. Thus, water samples were taken at the mine and surrounding groundwaters and rivers to characterize the chemical properties and environmental isotopes (δ2H and δ18O). The results showed that the quality and stable isotope ratios of AMD differed from those of groundwater/river water, indicating that the recharge areas of AMD. The recharge area of AMD was evaluated as the mountain slope at an elevation of 400–500 m while that of the surrounding groundwater was evaluated at an elevation of 350–450 m, by considering the stable isotopes ratios. This indicates that the groundwater affected by AMD is limited to the vicinity of the mine and distributed around nearby rivers.
