Removing Iron from Epsom Salt
« on: March 24, 2012, 11:26:23 AM »
Hy Everyone,

 I dont know if this is the right board for my question but since i'm undergraduate i think this is right board

 To make Epsom salt i add Sulfuric Acid to Magnesite but the magnesite contains some traces of Iron so along with Epsom salt (MgSo4) Ferrous Sulfate also forms (FeSo4)
how can i remove Ferrous Sulfate from Epsom Salt

 Can anyone help me?
 Take care

You might try fractional crystallization.  You could also try recrystallization from water/ethanol, because magnesium sulfate is more soluble in ethanol than ferrous sulfate.  Or, you know, just buy some epsom salts.
