Description
Ferrous sulfate is mainly used as an efficient flocculant for water treatment, an iron fertiliser supplement for agriculture, and an industrial raw material for preparing other iron-based compounds; the dataset contains the main raw and auxiliary materials, energy, atmospheric emissions and waste of the production process, and infrastructure such as the manufacture of production equipment and the construction of plant buildings is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources; the production activities of this product include titanium liquor preparation, titanium liquor purification, titanium liquor concentration, metatitanic acid preparation, metatitanic acid purification, titanium dioxide preparation, crushing and post-treatment. Ferrous sulfate is a by-product of this production process, allocated according to physical relationship (mass).

Process Description
The CAS number of ferrous sulfate is 7720-78-7. It is a light blue-green to white crystal that is easily soluble in water. The aqueous solution is acidic and is easily oxidized to ferric iron in the air and turns yellow. Its main uses are as an efficient flocculant for water treatment, an agricultural iron fertilizer supplement, and an industrial raw material for the preparation of other iron-based compounds.

Technology comment
During the production of titanium dioxide by the sulfuric acid method, a large amount of ferrous sulfate will be produced as a by-product. According to industry data, the titanium dioxide by-product method accounts for more than 75% of the total domestic ferrous sulfate production capacity and is the mainstream supply source.
