Do you know how to make magnesium sulfate heptahydrate?

Magnesium sulfate heptahydrate is a white crystalline solid with a wide range of applications. It is often used as fertilizer, feed, etc. in agriculture. So do you know the production method of magnesium sulfate heptahydrate? The following will share with you the production method of magnesium sulfate heptahydrate.

It is obtained by adding sulfuric acid to natural magnesium carbonate, and after removing carbon dioxide, it is obtained by recrystallization, and it is obtained by dissolving magnesium sulfate and vanadium in hot water for recrystallization. Alternatively, the bittern can be obtained by drying the salt in the sea water. After evaporating with the brine method, high-temperature salt is produced. The bittern can be immersed in a 200g/L MgCl2 solution at 48 degrees Celsius. The NaCl dissolves less, and the MgSO4 dissolves more. After separation, the immersion liquid is cooled to ten degrees Celsius to precipitate coarse MgSO4·7H2O, which can be obtained by secondary recrystallization to obtain magnesium sulfate heptahydrate.
