Magnetite, the most magnetic mineral on Earth, is increasingly being found in seafloor environments that are rich in iron and ...

Magnetite, Fe3O4, contains both ferrous, Fe+2, and ferric, Fe+3, ions. During FAC, the ferrous ions continually migrate from the magnetite layer at the affected areas (high fluid impingement ...
The magnetite layer protects the underlying steel from corrosion. However, dissolved oxygen (D.O.) in the feedwater will convert the magnetite to non-protective rust (hydrated Fe 2 O 3).
