2021-1-24 Overview of process control of novel calcification. The calcification‑carbonation process is a new method for recovering alkali and alumina from bauxite residue (red mud) and obtaining non-hazardous and near-neutral residue (calcification‑carbonation residue) simultaneously (Zhang et al., 2011a, Zhang et al., 2011b).This method consists of two basic steps: calcification and carbonation.

Bauxite - Wikipedia. Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 ...
