One of the factors that affect the composition of the bauxite residue is the type of the ore. Bauxite ores can be classified into three categories based on host-rock lithology. They are the lateritic bauxites (88 %), the karst bauxites (11.5 %), and the Tikhvin-type bauxites (0.5 %) [24, 25]. Bauxite deposits lying on carbonates are classified ...
