Technical Document

Brief Overview

Ferrous Sulphate Heptahydrate (FeSO₄·7H₂O) is a blue-green crystalline compound widely used in various industries, including water treatment, agriculture, and pharmaceuticals. It serves as an iron supplement in animal feed and fertilizers, a coagulant in wastewater treatment, and a precursor in pigment production.

Manufacturing Process

Ferrous Sulphate Heptahydrate is primarily produced as a byproduct of steel pickling, where iron reacts with sulfuric acid. The resulting ferrous sulfate solution is then crystallized and dried to obtain the heptahydrate form. Alternatively, it can be synthesized by reacting iron ore with sulfuric acid under controlled conditions.
