ferrous sulphate all kinds of type summarize.

the main 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

other source :

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

Now we talk the kind of ferrous sulphate.  ferrous sulphate is divided to two kinds according to its molecular formula .

ferrous sulphate heptahydrate  FeSO4.7H2O

ferrous sulphtae monohydrate  FeSO4.H2O

ferrous sulphate heptahydrate is light green powder.

ferrous sulphtae monohydrate is white or gray powder.

ferrous sulphate heptahydrate is also beed divided two kinds.

drying type; wet type

drying type has a good shelf time, it is about 12 mouths usually.

wet type has a short shelf time, it is about one mouths usually.  it may keep good two mouths in winter.

In international trade,  wet type is not proper for a long transportation for its short shelf time. if you do need, better in winter(China winter if you bur from China).

usually we suggest purchase dry type ferrous sulphate heptahydrate.

ferrous sulphate monohydrate is produce from ferrous heptahydrate by direct fired dryer.  

people may ask what is different between drying type ferrous sulphate heptahydrate and ferrous sulphate monohydrate.

one: they have different molecular formula. 

two: ferrous sulphate hepta usually be used in water treatment ,fertilizer, moss remove,dyeing ,

        ferrous sulphate mono usually be used in feed additive,pharmacy.  and it is more expensive than ferrous sulphate hepta.

hope my summary will help .
