Manufactured soil: A new use for bauxite residue
Plant growth in bauxite residue is limited by its saline-sodic nature and its high pH (pH 10-13) and alkalinity (Di Carlo et al. 2019). This is because alumina is refined by the Bayer procees in which the bauxite rock is digested in NaOH at high temperatures and pressures and residual Bayer liquid remains in the residue (Xue et al., 2016).
