Description
This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. Ferrous sulfate is mainly used as an efficient flocculant for water treatment, an iron fertilizer supplement in agriculture, and an industrial raw material for the preparation of other iron-based compounds; this dataset includes the main raw and auxiliary materials, energy, air emissions and waste of the production process, while infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources; the production activity of this product includes titanium liquor preparation, titanium liquor purification, titanium liquor concentration, metatitanic acid preparation, metatitanic acid purification, titanium dioxide preparation, crushing, post-treatment and other process steps, and ferrous sulfate is a by-product of this production process, allocated according to physical relationship (mass).
Activity Description
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, post-treatment and other processes.
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.
