MAGNESIUM SULFATE Chemical and Technical Assessment

Magnesium sulfate occurs naturally in seawater, mineral springs and in minerals such as kieserite and epsomite. Magnesium sulfate heptahydrate is manufactured by dissolution of kieserite in water and subsequent crystallization of the heptahydrate. Magnesium sulfate is also prepared by sulfation of magnesium oxide. It is produced with one or seven

4. Magnesium sulfate

Magnesium sulfate forms various hydrates in aqueous solution. Experiments have been conducted with two phases, the heptahydrate, MgSO4 • 7H2O, also referred to as epsomite, and the hexahydrate, MgSO4 • 6H2O, known as hexahydrite. A comprehensive study of the influence of additives on thermodynamics and kinetics of crystallization of
