Bayer precipitates from the seawater neutralization of Bayer liquor waste from the alumina industry are shown to be a prospective solution for the remediation of acid mine drainage (AMD) water. Precipitates are varied in composition, albeit they are generally comprised of hydrotalcite (MgAl(OH)CO∙HO), calcite (CaCO), aragonite (CaCO), mixed metal hydroxides (MgAl(OH)), and halite (NaCl). Brucite (Mg(OH)) is detected for lower Bayer liquor concentrations (1-3 g L AlO) when the concentrations of aluminum and hydroxyl species are insufficient to promote hydrotalcite formation.
