초록

본 연구에서는 석탄 광산배수에 함유된 중금속을 부유선별로 제거하기에 앞서 부유선별 조건에 영향을 미치는 철, 망간, 알루미늄 이온의 침전특성을 알아보았다. Fe(III), Mn(II), Al(III) 이온을 NaOH와 반응시켜 1 h 동안 침전시키면 Fe(III)은 pH 5.0 이상에서, Mn(II)은 pH 10.0 이상에서 그리고 Al(III)은 pH $6.0{\sim}9.0$의 범위에서 대부분 침전되어 여액에 $1.0mgL^{-1}$ 이하로 잔류되었다. Fe(III), Mn(II), Al(III)의 혼합 용액에 포수제인 올레인산나트륨을 첨가하였을 경우, 각각의 중금속 이온은 올레인산나트륨과 반응하여 불용성 염을 거의 형성하지 않았기 때문에 침전 부선법으로 광산배수에 함유된 중금속을 제거해야 하는 것으로 나타났다.

This study has been carried out in order to examine the precipitation characteristics of Fe, Mn and Al ions in coal mine drainage before removing heavy metals by using the froth flotation method. The removal rate of Fe(III), Mn(II) and Al(III) within 1 h accounted for over 99% in pH 5.0, 10.0, and $6.0{\sim}9.0$ respectively, and residual concentrations of which were under $1mgL^{-1}$. When sodium oleate as a collector was added to the solution of Fe, Mn, and Al ions, insoluble salts was not formed by the reaction of heavy metal and sodium oleate. So, we must remove the metals from coal mine drainage by using not the ion flotation method, but the precipitation flotation method
