Abstract

Mine drainage and yellowish brownish precipitation (so called "yellow boy") in the Ichinokawa mine, Saijyo City, Ehime prefecture, Japan, have been geochemically investigated. The mine drainage reaching the Ichinokawa River originates in the Senga gallery of the Ichinokawa mine. The Ichinokawa mine drainage is characteristically high in arsenic and exceeds the water-quality standard on arsenic. The yellowish brownish precipitation is characterized by high iron, arsenic and antimony contents. It is supposed that the Ichinokawa mine drainage has been formed by pyrite weathering. The drainage does not have a negative impact on the water quality of the Ichinokawa River. However, the Ichinokawa rivers may be degraded by the Ichinokawa mine drainage in future.
