Iron(II) sulphate monohydrate neutralised is mainly used in the cement industry for reduction of hexavalent chromium.

Enrichment of cement with dry ferrous sulphate reduces the content of chromium, which is known to cause stinging and allergies. The EU directive requires that all cement manufacturers reduce the chromium compounds.

KNOWLEDGE BASE

Iron(II) sulphate as an intermediate manufactured during the production of TiO2

Generally, titanium dioxide is white, but has a slightly yellowish color due to the absorption of the visible light portion of the particles corresponding to the blue color.

Iron sulphate – respected intermediate product used in the chemical industry

For many years, ferrous sulfate is used for production coagulants and wastewater treatment. It is also used for the production of iron pigments. In the cement industry is used as the reducing agent of hexavalent [...]
