Sažetak

In order to study the kinetics and mechanism of the reaction, laboratory digestions were carried out of industrially produced gibbsite mineral y-Al(OHl3 in aqueous solutions containing an excess of sodium hydroxide. Reaction temperature, duration and base concentration were varied. From the results obtained basic kinetic parameters were computed: reaction rate constants (k)and process activation energy (Ea).
