Introduction
There has been increasing interest in and research into the utilisation of industrial residues for remediation of degraded soils (e.g. Ho et al. 1989; Summers 1996; Vangronsveld et al. 1999; Lombi et al. 2001; Lin et al. 2002). The successful applications of such technologies create conduits for turning industrial wastes into products that can be used for ecological rehabilitation.
Bauxite residue (red mud) from alumina production is an abundant industrial residue. Raw red mud frequently contains high levels of sodium hydroxide and is highly basic (pH > 10). Costly engineering work is usually required for the storage of this potentially ...
