Uses
Primary
- WHO LEM ("ferrous salts" for antianemia)
- Production of sulfur trioxide
Natural occurrence
- Heptahydrate occurs naturally as the mineral melanterite as well as several others.
Hazards
Production
Extraction
- Iron (III) sulfate occurs naturally as melanterite
- It is possible to hydrate marcasite, producing a mixture of iron (III) sulfate and sulfuric acid
- 2 FeS2 + 2 H2O + 7 O2 → 2 FeSO4 + 2 H2SO4
- It seems like this reaction should be sped up by zinc oxide:
- 2 FeS2 + 2 ZnO + 7 O2 → 2 FeSO4 + 2 ZnSO4
