We supply Ferrous Sulphate Heptahydrate, a versatile compound employed primarily as a fertilizer. Additionally, it serves as a mordant in the dyeing process of wool, contributes to ink manufacturing, and acts as a substitute for aluminum sulfate in water purification. Characterized by its green, monoclinic crystal structure, Ferrous Sulphate Heptahydrate is produced either as a by-product during the manufacturing of Titanium Dioxide or as a result of the pickling process in steel production.
