Abstract

AMD waters usually contains elevated concentrations of sulfate, iron and other contaminant metals (Pérez-López et al., 2009). Essentially, treatment of AMD water consists of acid water neutralization and precipitation of metal contaminants. A common, used passive system is the Anoxic Limestone Drainage (ALD) that consists of ditches filled by limestone gravel. Acid water circulates through it, dissolving limestone (calcite) and increasing pH. Iron and aluminium are retained as hydroxides and sulfate as gypsum.
