文摘In this study,the physical and chemical characteristics and direct aqueous mineral carbonation of red gypsum have been investigated.The characterization studies showed that red gypsum is a very potential feedstock for mineral carbonation.It is mainly consisted of CaO,Fe2O3 and SO3 along with some impurities.On the other hand,the carbonation results showed that direct aqueous carbonation of red gypsum resulted in CaCO3 and FeCO3 production,however,the carbonates purity and carbonation efficiency are still very low.
