Alkalinity conversion of bauxite refinery residues by neutralization

Red mud remains the largest environmental issue for the alumina industry due to its high pH (>13), fine-grained nature (>90% is 50 g/kg), and soluble alkalinity (≈30 g/kg as equivalent CaCO 3), which reduce the transport and reuse options of red mud. The neutralization of red mud provides pote...
