Abstract

A study was carried out to evaluate the remaining alkalinity producing capacities and reuse potential of the used limestone from successive alkalinity producing systems (SAPS) when limestone would be excavated to ameliorate. With two reactors having limestones and cow manure as substrates and mine waters as reacting medium anoxic environment was created in the plastic containers, in the laboratory. The limestone was retrieved for comparison of its alkalinity production potential. When the limestone samples retrieved from reactors, redox potential was lowered below -300 mV, dissolved oxygen reduced to less than 1 mg/L, alkalinity reached 1500 mg/L CaCO3 or more. The limestone from the reactor with higher acidic mine water produced about a 300 mg/L CaCO3 of alkalinity while the one less acidic produced around a 130 mg/L CaCO3. After washing both the limestone samples, it was observed that these still produced alkalinity of about 100 mg/L CaCO3, though less than the 130 mg/L CaCO3 of the fresh limestone. It meant that the limestones that are removed when repairing SAPSs on sites, could be reused.

연구의 목적은 현장 Successive alkalinity producing system 조를 보수할 때 굴착되는 석회석의 재이용 가능성을 평가하는 것이었다. 실내에서 석회석, 우분 및 광산배수가 포함된 반응조를 조성한 후 환원환경으로 변했을 때 석회석을 회수하여 알칼리도 생성과 중화 능력을 평가 하였다. 회수시 반응조 수질은 EC -300 mV 미만, DO는 1 mg/L 이하, 알칼리도는 1,500 mg/L CaCO3 이상이었다. 산도가 높은 광산배수에서 회수된 석회석은 약 300 mg/L CaCO3 알칼리도를 생성한 반면 산도가 낮은 석회석은 약 130 mg/L CaCO3 전후의 알칼리도를 생성 하였다. 이들 석회석을 세척한 결과 모두 약 100 mg/L CaCO3 의 알칼리도를 나타냈다. 따라서 환원상태로 있는 현장 SAPS 조의 석회석 경우 재이용 가능성이 있을 것으로 판단되었다.
