Abstract
Amelioration of Bayer-sinter bauxite residue (BSBR) is a prerequisite for the establishment of direct revegetation for the rehabilitation of a BSBR storage facility. A glasshouse study was conducted to elucidate the dynamics of the biogeochemistry of BSBR during rehabilitation. Addition of microbial inocula and organic matter to BSBR significantly lowered the pH and EC and restored a diverse microbial community in the BSBR in 30 days. Calcium mineral dissolution was observed and correlated with the dealkalization and desalination of BSBR. These promising results demonstrated the feasibility of such rehabilitation strategies for BSBR.
