Study on crystallization of calcium carbonate from calcium sulfate and ammonium carbonate in the presence of magnesium ions

Batch reactive crystallization of calcium carbonate (CaCO3) from ammonium carbonate ((NH4)2CO3) and calcium sulfate (CaSO4) was investigated in the presence of magnesium (Mg2+) ions. It was observed that Mg2+ ions partly inhibited the conversion of CaSO4 into CaCO3. When the content of Mg2+ was less...
