Fertilizer Manufacturing Process [2021] | Synopsis Chemitech

Catalysts such as magnetite (Fe3O4) have been used to improve the speed and efficiency of ammonia synthesis. Any impurities are removed from the ammonia, and it is stored in tanks until it is further processed. While ammonia itself is sometimes used as a fertilizer, it is often converted to other substances for ease of handling.
