It can be seen that the Ro of iron oxide oxygen carrier increases with the reduction degree of Fe2 O 3. When it is reduced to Fe 3 O 4, the Ro only reaches to 0.03, the lowest one in the list. Meanwhile, if the Fe 2 O 3 is fully reduced to Fe, the Ro can be 10 times higher to 0.3, second only to CaSO 4 /CaS (0.47).

Haematite and magnetite are the most commonly found iron ore minerals. The smelting process allows the iron ore to be heated with carbon. The carbon combines with the oxygen and carries it away, leaving behind iron. Blast furnaces are so hot which is why they melt the iron, and drain it off to be poured into moulds to form bars, called ingots.
