Ammonium sulfate preparation from phosphogypsum

2017-1-1  1. Introduction. Ammonium sulfate is found in the most everyday applications because of their unique chemical and physical properties. Ammonium sulfate is used in the agricultural fertilizer as a source of nitrogen and sulfur for plant nutrients (Schwenke & McMullen, 2009).Ammonium sulfate is a mixed fertilizer which contains nitrogen and sulfur nutrients (FAO, 2003, Tisdale, 2002).

Resource Potential of Natural and Synthetic Gypsum

2016-1-1  14.1. Introduction. About 100–200 million years ago, the mineral gypsum (calcium sulfate dihydrate [CaSO 4 ·2H 2 O]) became precipitated as a result of the evaporation of seawater. It is deposited in sedimentary layers in the marine environment. Under high pressure and temperature, gypsum is transformed into anhydrite (CaSO 4).In nature, gypsum and anhydrite occur as beds or nodular masses
