Iron ore - Wikipedia

DSO deposits are typically rarer than the magnetite-bearing BIF or other rocks which form its main source or protolith rock, but are considerably cheaper to mine and process as they require less beneficiation due to the higher iron content. However, DSO ores can contain significantly higher concentrations of penalty.

Corrosion process - Con-Rehab AS

Without intervention, iron and steel will want to give up the trapped energy and revert back to the iron ore state - we call this process “corrosion” or “rusting”. In chemical terms, we can write the corrosion process as: 4 Fe + 3 O2 → 2 Fe2O3 .(3) Iron + oxygen (air)→ Rust Equation (3) describes 4 atoms of iron (Fe) combining.
