The dissolution of aluminum hydroxides from bauxite ores constitutes a key process in the
aluminum industry. Generally, aluminum minerals in bauxites are present in the form of
gibbsite and/or boehmite. Kaolinite, an aluminosilicate that is also present in bauxites, is a
critical contaminant of the process. The understanding of the effect of the bauxite
composition and of the process variables on the kinetics of dissolution can lead to the
development of kinetic models and allow for subsequent process optimization. In this work …
