3. Production process
In the finishing of steel prior to plating or coating, the steel sheet or rod is passed through pickling baths of sulfuric acid. This treatment produces large quantities of iron(II) sulfate as a by-product.
Fe + H2SO4 FeSO4 + H2
Another source of large amounts results from the production of titanium dioxide from ilmenite via the sulfate process.
Ferrous sulfate is also prepared commercially by oxidation of pyrite:
2 FeS2 + 7 O2 + 2 H2O 2 FeSO4 + 2 H2SO4

4. Usage:
Ferrous Sulfate is used in feed, preserves, waste water treatment and water purity, disinfection, rubber, leather, washingpowder, livestock feed, pencils.
