    The latter is desulphated using CaCl2 generated in the process itself and thereafter evaporated to obtain carnallite crystals from which KC1 is recovered while the liquor rich in MgCl2 serves as a source of MgCL. The gypsum produced during desulphatation is reacted with aqueous ammonia and CO2 to produce ammonium sulphate and calcium carbonate.

    Nov 16 2015 In principle the gypsum waste could be used to capture several hundred megatonnes of carbon dioxide CO 2. For example when gypsum is converted to ammonium sulfate NH 4 2 SO 4 with ammonia NH 3 and CO 2 also solid calcium carbonate CaCO 3 is generated. The ammonium sulfate can be utilized as a fertilizer or in other mineral .
