Treatment of Acid Mine Drainage using Magnesium Hydroxide

The integrated limestone and Fe(II)-oxidation process was developed, which allows the oxidation of Fe(II) when limestone alone was used for neutralization (Maree, 1997). In this process powdered limestone was used for Fe(II)-oxidation at pH 5.5, neutralization of free acid, metal precipitation (e.g. Fe 3+ and Al ) and gypsum crystallization, all in
