Kinetics of gibbsite and boehmite digestion

In order to determine the digestion process mechanism and kinetics, laboratory digestion processes have been carried out in industrially and synthetically produced gibbsite and boehmite minerals, and also in bauxite samples. Digestion processes have taken place in laboratory reaction vessels, i.e. autoclaves with varying temperatures, reaction times and base concentrations. The experimental results have been processed mathematically in order to determine the basic kinetic parameters: reaction rate constant (k) and process activation energy (E_a).
