Bauxite an overview ScienceDirect Topics

Bauxite is a reddish-brown clay-like deposit containing iron, silicates and aluminium oxides, the latter comprising the largest constituents. At present, bauxite is so plentiful that only deposits containing a content of aluminium oxides greater than 45% are selected to manufacture aluminium.The XRD patterns of paste samples with different bauxite tailings content and different powder selection frequencies of bauxite tailings at different curing ages are presented in Fig. 9. The hydrate products of the pure cement sample T0 principally contained clinker phases (C 3 S and C 2 S), ettringite, CaCO 3 and Ca(OH) 2.Hydration kinetics of cement-calcined activated bauxite tailings
