Bauxite is purified by the Bayer process which is the principal industrial refining process As bauxite contains only about 40 to 50% of alumina the rest has been removed This is achieved by washing bauxite with hot sodium hydroxide which dissolves the alumina by converting it to aluminum hydroxide which forms a solution in a strong base
The calculation of the Ce anomaly with Ce linearly interpolated between La and Pr is given by the following equation De Baar et al 1983 5 Ce / Ce ∗ = 2 Ce SN / La SN Pr SN However many natural waters biogenic or authigenic precipitates and biogenic sediments display La anomalies thereby biasing the determination of the Ce
