The new process takes waste gypsum or chalk and purifies it so that it can be used as high-grade white filler in plasterboard and cement. Firstly, impure gypsum is placed into a solution of ammonium sulfate around 90–100°C, together they form a complex. This complex sinks into the solution, releasing any impurities in the gypsum.

The reactivity of flue gas desulphurization gypsum with ammonium carbonate has been studied in the temperature range (20–50) °C. Mechanism of this reaction was suggested and the kinetics parameters characterizing the reaction were determined. A mathematical model suitable for the prediction of the conversion of gypsum was proposed.
