1 Introduction. Red mud is a slimy caustic residue generated from alumina refining of bauxite ores. During the alumina extraction process, about 35 %–40 % of the bauxite ores go into the residue as highly alkaline red mud slurry (pH 10.0–12.5) which contains 15 %–40 % of solid phase in volume [ 1, 2 ]. Depending on the quality of bauxite ...Web
