Celestite ore (SrSO4) is used as raw material for the production of strontium compounds. The aim of this study is to develop a new and efficient strontianite (SrCO3) production method. Strontianite was obtained from domestic celestite concentrate with direct conversion method in which celestite reacts with CO3 2- and NH4 + containing solution. Thus, the effect of particle size, time, ammonia concentration on the conversion was investigated. NH4)2CO3 solution was used as carbonate agent. Because the solution is decomposed at 58 °C, experiments were performed low temperatures. Celestite ore was converted to strontianite between 3 and 6 h depending on ammonia concentration and celestite mass. Characterization of celestite ore, products and reaction residues were carried out by DSC, TG, XRD, and AAS analytical techniques.
