Applications:
The Iron(II) sulphate is mainly used in manufacture of ferrous coagulants for water purification and wastewaters treatment. It is used also for production of iron pigments. In cement industry it serves for reduction of hexavalent chromium. In agriculture it is used as a component of fertilizing mixtures and in feeds is a rich source of microelements.
