The main raw material of Ferrous sulfate monohydrate is Ferrous sulfate heptahydrate/Copperas, which is light green and blue crystal and is from the Titanium Dioxide factory.

Raw material ferrous sulfate heptahydrate/ iron sulphate heptahydrate is very wet and contains a little waste acid and Titanium, and will corrode metal and cement, but the processed ferrous sulfate hepta contains just a little impurity and has no corrosion, it’s very clean.

The manufacturing process of ferrous sulfate monohydrate is very easy, usually, there are two ways, as follows:
Method one:
Ferrous Sulfate Heptahydrate (Raw Materials)
Using water for wash in Cleaner
(Wipe Off Surface Impurity)
Reactor of Solution
(Heating reactor dissolved materials to re-crystallized)
(Wiping off Water)
Drying (Ferrous Sulfate Monohydrate Powder 30-31%)


The color of ferrous sulfate monohydrate produced with this method is very beautiful and with low content of impurity, but it can only load 20-22MT goods in a 20 feet container. And it makes no granular
Method two:
Ferrous Sulfate Heptahydrate 
(Raw Materials)
Using water for wash in Cleaner
(Wipe Off Surface Impurity)
Rolling Forward in Rolling Kiln
(In Temperature of 380-500 degrees)
(Taking off 6 Crystallization Water Molecule)
The color of ferrous sulfate produced with this method is not so beautiful as the method one, but it can load 27MT max into a 20 feet container. Finished goods can be shaped as 6-12/12-24/20-40/60-80 mesh
