Difference Between Gypsum and Limestone Compare the
Nov 04, 2011 The key difference between gypsum and limestone is that the calcium sulfate is the main constituent in gypsum whereas calcium carbonate is the main constituent of limestone.. Limestone and gypsum are minerals that form from calcium salts limestone contains calcium carbonate while gypsum contains CaSO 4 2H 2 O. However, their properties and usages are different from each other.
ammonium sulfate production from gypsum
the technical feasibility for producing the dual commercial products, ammonium sulfate fertilizer and precipitated calcium carbonate, from this gypsum Ammonium sulfate is a valuable nutrient source for providing both nitrogen and sulfur to growing plants There is a growing demand for sulfur in the sulfate form as a plant nutrient.

production of ammonium sulfate from gypsum
Ammonium Sulfate an overview ScienceDirect Topics. Ammonium sulfate is produced by three different processes 1 Ammonium sulfate also is manufactured from gypsum CaSO 4 2H 2 O In this process, finely divided gypsum is added to a solution of ammonium carbonate causing calcium carbonate precipitates as a solid, leaving ammonium sulfate in the solution N H 4 2 C O 3 CaSO 4 N H 4 2
CONTINUOUS PRODUCTION OF FERTILIZING SALTS WITH
This excess of ammonium carbonate used is recovered in order to recycle it in the process and to isolate the ammonium sulphate which may be treated continuously with a lime carbonate or oxide, recovering the gases evolved by the reaction and obtaining as final product lime sulphate gypsum.
