초록

동해탄광 일대에서 산성광산배수가 유입되는 하천의 바닥에는 적갈색과 황갈색의 침전물이 형성되고 있다. 이 침전물에 대한 X-선 회절분석 결과 적갈색 침전물은 대부분 페리하이드라이트이며 소량의 침철석을 포함하고 있는 반면에 황갈색 침전물은 슈워트마나이트로 구성되어 있다. 열분석과 가열 실험에서 페리하이드라이트와 슈워트마나이트는 약 $400^{\circ}C$에서 결정도가 낮은 적철석으로 변화하며 $700 ^{\circ}C$에서는 결정도가 높은 적철석으로 변화한다.

The ochreous precipitates, reddish brown and brownish yellow in color, are pre- cipitated in the stream bottom of acid mine drainage (AMD) in the Donghae coal mine area. X-ray diffraction analysis shows that the reddish brown precipitate consists mainly of ferrihydrite with small amount of goethite, while the brownish yellow precipitate of schwertmannite. Thermal experiments show that ferrihydrite and schwertmannite partially convert to poorly-crystallized hematite at $400^{\circ}C$ and to well-crystallized hematite at $700^{\circ}C$.
