Investigation of Factors Controlling the Dissolution of Cobalt Oxide Co3O4 Under Bead Mill Operation Conditions

Abstract—The experimental data obtained on the effects of catalyst nature, acid concentration and type, and the mass of cobalt oxide on the kinetics of dissolution of cobalt oxide (Co3O4) in a vertical bead mill using glass beads as an additional inert solid phase, employed to intensify the process via mechanical surface activation, can be taken into account and used to optimize practical processes related to the dissolution of Me3O4 type oxides.
