Low cement castable is the castable whose CaO content less than 3%, usually the refractory cement dosage is from 38%, but high grade cement is needed to ensure the strength of the castable. Comparing to common refractory castable, low cement castable has better performance in high temperature, and require less water, it makes the castable has lower .

During the Bayer process for alumina production, the molecular formula of the bauxite residue is approximately equivalent to Na 2 O·Al 2 O 3 · 2 ·nH 2 O. This means that 1 kg of SiO 2 in bauxite will produce 1 kg of Al 2 O 3 and kg of Na 2 O in bauxite residue. Thus, the extraction efficiency of alumina is low when processing lowgrade bauxite.
