Question

Wrought iron is manufactured by melting cast iron in a furnace with a hearth lined by $F e_{2} O_{3}$ . How many of the reactions given below are involved in this process, called the "Puddling process"?

$F e_{2} O_{3} + 3C \to 2 Fe + 3CO$

$2F e_{2} O_{3} + 6S \to 4Fe + 3S O_{2}$

$2F e_{2} O_{3} + 3Si \to 4Fe + 3Si O_{2}$

$F e_{2} O_{3} + 3Mn \to 2Fe + 4 MnO$

$MnO + Si O_{2} \to MnSi O_{3}$

$5F e_{2} O_{3} + 6P \to 10Fe + 3 P_{2} O_{5}$

$P_{2} O_{5} + F e_{2} O_{3} \to 2FePO_{4}$

$F e_{2} O_{3} + MnO \to FeMnO_{4} + F e$
