Ammonium Sulphate - China

Brief Overview
Ammonium sulfate is an inorganic salt characterized by the chemical formula (NH4)2SO4. While this compound finds diverse industrial applications, caution is advised in its handling due to potential hazards to human health. Its principal role is as an agricultural fertilizer, boasting a composition of 21% nitrogen and 24% sulfur. In its natural state, ammonium sulfate is encountered as the mineral mascagnite, which is relatively rare and can be found in volcanic fumaroles and coal fire dumps.
Manufacturing Process
Ammonium sulfate is produced through a process involving the reaction of ammonia with sulfuric acid, as represented by the chemical equation:
2NH3 + H2SO4 → (NH4)2SO4
Alternatively, another method for the preparation of ammonium sulfate involves introducing gypsum salt to an ammonium carbonate solution. This reaction results in the formation of calcium carbonate and ammonium sulfate as products. The calcium carbonate precipitates out of the mixture, leaving behind a solution containing ammonium sulfate.
