The Method Of Production

When the steel is on the verge of completion just before it is passed through pickling baths, the steel rods or sheets are dipped in sulphuric acid. This method produces a lot of ferrous sulphate as a by-product.

Another method of production is by manufacturing titanium dioxide from ilmenite through the sulphating process. And if you talk about its commercial production method then there is another way. It is manufactured by the oxidation of pyrite. It can also be manufactured by the displacement of metals which are less reactive than iron. It is done from their sulphate solutions.

There is another method of production of Ferrous Sulphate Heptahydrate Crystals. It is done by converting ferrous sulphate monohydrate crystals. It is converted in a crystallization reactor with water. The resultant product is Ferrous Sulphate Heptahydrate Crystals. The water that had been used is now isolated and drained away.
