Abstract

To evaluate the potential of adjacent area pollution by Acid Mine Drainage from the geologic materials found in the tailings and mine waste at the abandoned Jeonjuil mine site, located in the southern part of Korea, a geochemical study involving acid-base accounting(ABA) test and sequential extraction tests were performed. The results of the chemical analysis showed that the maximum potential acidity (MPA) of mine waste materials was 107.41kg H2SO4/t, and maximum acid neutralizing capacity (ANC) was 75.529kg H2SO4/t. In addition, pH1:2 and EC1:2 (solid : water) of sample were 3.0 to 8.35 and 59.9 μS/cm to 784μS/cm, respectively. These geochemical characteristics suggest that these samples with sulphide mineral are exposed to oxidant environment and thus have acid producing salts. However, the result of total sulfur content and the ANC data, collected at the tailings, showed the very little possibility of the ARD occurrence in this area. All tailing samples were classified as non-acid forming (NAF). Also, the results of the examination by Soil pollution official examination methods, sequential extractions and KSLP and TCLP do not warrant any pollution.

본 연구는 전주일 광산의 광미 및 폐석으로부터 발생된 산성광산배수가 주변지역을 오염시킬 위험성을 평가하기 위해 지구화학적 특성을 연구하였다. 광미시료에 대해서 연속추출 및 산-염기평가시험을 수행하였다. 화학적 분석 결과 지질시료 중 최대로 발생 가능한 황산(H2SO4)양은 최대 1톤 당 107.41kg로 나타났고 중화능력(ANC)은 최대 75.529kg H2SO4/t 으로 나타났다. 또한, pH1:2 및 EC1:2가 각각 3.0 ~ 8.35 및 59.9 ~ 784μS /cm로 측정되는데 이러한 지구화학적 특성은 현장에서 이미 황화광물 산화작용이 상당히 진행된 것을 의미한다. 광미 시료는 모두 비산발생 영역에 들어간다. 따라서 광미시료는 AMD 발생문제가 우려되지 않는 것으로 판단된다. 그리고 토양오염공정시험, 연속추출, KSLP 및 TCLP 결과 오염우려가 없는 것으로 판단된다.
