The production method of magnesium sulphate heptahydrate price is sulfuric acid method, which

uses magnesia, also known as magnesia, as the raw material. Add water or mother liquor to the

neutralization reactor, and then slowly add sulfuric acid and light calcined powder containing over

85% magnesium oxide in a certain ratio to the reactor for neutralization reaction. Control Ph=5,

and the concentration is 39-40. Stir for 30 minutes to allow the reaction to proceed fully. The

neutralization solution is maintained at 80 ℃ by MgO+H2SO4+6H2O → MgSO4 · 7H2O, and

the filtered filtrate is sent into the crystallizer. An appropriate amount of crystal seeds are added,

and then cooled, filtered, centrifuged, and dried at 50-55 ℃ to obtain magnesium sulfate.
