According to (Burnett et al., 1996; Bouargane et al., 2020; Idboufrade et al., 2021), the principal advantage of a Merseburg process is that the radionuclides initially contained in PG were not transferred to the ammonium sulfate but were accumulated and migrated preferentially into the precipitated by-product, calcium carbonate.
The process for manufacture of ammonium sulfate from gypsum, known as the Merseburg Process, named for the town in Germany where it was developed, has been …
posted on 7-9-2012 at 08:49. Merseburg Process. In light of all of the copper sulfate and sulfuric acid synthesis question threads, I was thinking that a discussion of a kitchen-friendly version of the Merseburg Process (or rather, the Ammonium Carbonate-Gypsum Process) would be in order. Merseburg Process: (NH4)2CO3 + CaSO4 --> …
Two synthesis methods were used for the conversion of phosphogypsum to ammonium sulfate and calcium carbonate: (i) Two-step method: it consists of reacting ammonia aqueous solution with CO 2 to produce ammonium carbonate. This last product reacts with PG to form ammonium sulfate (NH 4) 2 SO 4 and calcium carbonate CaCO …
One of the ways of utilizing FGD gypsum is a conversion reaction with CO 2 and ammonia with the formation of ammonium sulfate and calcium carbonate. This conversion process for gypsum is not new. It was carried out for the first time on an industrial scale in Merseburg (Germany) in 1909 [2]. Therefore, it is often called the …
