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 ...

Sulfuric acid (H 2 SO 4) is important in the production of fertilizers (e.g., ammonium sulfate (sulfate of ammonia), (NH 4) 2 SO 4, and superphosphate, Ca(H 2 PO 4) 2, which is formed when rock phosphate is treated with sulfuric acid). Sulfuric acid is manufactured at the site using the well-known contact process.
