To understand water mass balance and behavior of major elements in river basin is an important issue in advancing the management of abandoned and closed mines. This paper describes the response of river runoff due to rainfall, and the relationship between water mass balance and river water quality. In the river basin around the Ningyo-toge Mine, the runoff increased when it rained more than 50 mm d–1 and continued for several days after the rain, while in case of heavy rain over 500 mm, the effect of intermediate runoff extended to the next month. The river water quality was Na– Cl type in the upstream, while it was Na–HCO3 type or Ca–HCO3 type in the middle to downstream, and contained dissolved Si in the entire river basin. Based on the measured anions and cations, it is inferred HCO3 and Ca2+ results from the dissolution of carbonate minerals, and that Na+ and Cl– are derived from sea salt. Since a correlation between the concentration of Si and runoff was observed, the Si concentration may be regulated by both groundwater flow to the river and the dissolution rate of feldspar.
了解流域水质量平衡及其主要元素的变化规律，是推进废闭矿山治理的重要问题。本文阐述了降雨对河流径流的响应，以及水质量平衡与河流水质的关系。在宁窑托格矿区周边流域，降雨量大于50 mm d-1时，径流增加，并在雨后持续数天，大于500 mm暴雨时，中间径流的作用延续到下个月。河流水质上游为Na - Cl型，中下游为Na - hco3型或Ca-HCO3型，整个流域均含溶解Si。根据测定的阴离子和阳离子，推测HCO3和Ca2+来自碳酸盐矿物的溶解，Na+和Cl -来自海盐。由于Si浓度与径流之间存在相关性，因此Si浓度可能受到流入河流的地下水和长石溶解速率的调节。

Acid mine drainage (AMD) releasing from abandoned mines in Japan sometimes contains a high level of manganese (Mn) over the effluent standard (10 mg dm–3) with cadmium (Cd) and zinc. Cadmium is normally precipitate as hydroxides at pH 9–10, while it can be removed at a lower pH range of approximately 8–9 by surface complexation with metal hydroxides such as ferrihydrite and gibbsite. In this study, we examined the removal performance of Cd by manganite (γ-MnOOH) which is trivalent Mn oxide by an adsorption experiment, and found the Cd concentration decreased over pH 9.0 below the effluent standard (0.03 mg dm–3), which the surface complex equilibrium constant was Log K = –4.0. A neutralizing experiment of the AMD containing Mn (39 mg dm–3) and Cd (0.077 mg dm–3) from the X mine showed the Cd was removed at pH 8–10, and a chemical equilibrium calculation revealed the surface complexation on γ-MnOOH was the main removal mechanism. Our results therefore suggest the Mn oxidation and surface complexation with the product is the controlling factor Cd removability during the neutralization of AMD containing Mn.
