백운석 광산에서 발생되는 분진세척수에 대하여 응집침전에 의한 탁도제거 특성과 분진을 활용한 산성광산배수 중화처리 가능성을 평가하였다. 실험을 위해 S 백운석 광산의 분진을 이용해서 인공 분진 세척수를 제조하였다. 초기 탁도는 1,558 NTU 였으며, pH는 8.51이었다. 분진의 중수위 입도(D50)는 16.4 μm 였으며, 대부분이 10～30 μm의 입자크기를 갖고 있었다. 응집제와 관계없이 pH 3과 5에서는 90%이상의 탁도가 제거되었다. 무기 응집제인 PAC의 경우 pH 7에서, 유기응집제인 Nalco 9601의 경우 pH 11에서 탁도제거 효율이 좋았다. 산성광산배수에 대한 중화능력 실험 결과 백운석 분진은 10분경과 후 pH 2.89인 산성광산배수의 pH를 6.7 이상으로 상승시켰고, 용존되어 있던 Fe와 Al을 100% 제거하였다.
Abstract
The improvement of turbidity in a dolomite mine dust screen water by coagulation and precipitation and the feasibility of neutralizing acid mine drainage (AMD) using the dust were investigated. The simulated dust screen water was prepared using S dolomite mine dust for experiments. The water shows 1,558 NTU of turbidity and pH 8.51. The median diameter (D50) of dust was 16.4 ㎛ and the particle size distributes from 10 ㎛ to 30 ㎛. Regardless of the coagulants, 90% of turbidity was improved at pH 3 and 5. The inorganic coagulant, PAC, and the organic coagulant, Nalco 9601, show good improvement efficiencies of turbidity at pH 7 and 11, respectively. In the experiment to neutralize acid mine drainage, dolomite dust increased the AMD pH from 2.89 to 6.7 for 10 min, and removed 100% of the dissolved Fe and Al.
