Determination of Aluminum in Bauxites by Fluorate Replacement-EDTA Titrimetry

A method for the determination of Al2O3 in bauxite samples with high-Fe by fluorate replacement EDTA titrimetry was reported in this paper. The factors influencing the determination of Al2O3, such as dosage of replacement reagent KF and reaction (boiling) time were studied. The method has been applied to the determination of Al2O3 in practical bauxite samples and the results were in agreement with quality management regulation.
