Brief description Pelletisation of seawater-neutralised bauxite refinery residues (Bauxsol?) for construction of permeable reactive barriers to treat flowing acid mine waters. Acid mine drainage (AMD) occurs where sulphides (mostly pyrite, but also sulphides of other metals) are exposed to oxygen and water; the estimated global liability from AMD is over US$300 billion. There is currently no cost-effective way to prevent the release of acid and heavy metals from exposed sulphide minerals especially at abandoned mine sites. This study investigates the pelletisation and use of neutralised bauxite refinery residues (Bauxsol?) to treat flowing metal-rich acid mine drainage waters using reactive-barriers that will neutralise acid and remove heavy metals without impeding flow.
