Ferrous Sulphate Heptahydrate (Recycled) - China

Brief Overview
Iron (ll) sulfate exist most commonly as heptahydrate form and it is highly soluble in water to produce the complex [Fe(H2O)6]2+, which has octahedral molecular geometry and is paramagnetic.
Manufacturing Process
Ferrous sulfate monohydrate is obtained from a pickling solution containing ferrous chloride, hydrochloric acid and water and reacted in a precipitating reactor in the presence of excess sulfuric. Ferrous sulfate monohydrate is then converted in a crystallization reactor in the presence of water into ferrous sulfate heptahydrate as crystallized product. After which, water is isolated from the ferrous sulfate heptahydrate.
