Abstract

Iron-ore tailings filled in a soil column were leached daily with deionized water at various pH 5, 6, 7, 8 and 9) for 50 days. There was a continuous decline in conductivity of all leachates during the study. The final conductivity values of all leachates were significantly lower (P < 0.001) than the initial values. Final pH values were all in the range 8.2-8.3. The lower pH treatments resulted in high leachate concentrations of magnesium, manganese, iron, lead, and zinc. Sodium, potassium and calcium concentrations were similar for all treatments. Copyright © 1988 by SAGE Publications.
