Why iron pyrite is not the ideal choice of ore for the extraction of iron?

  • Correct answer
    A
    It produces polluting gases
  • B
    Thermodynamically not fessible
  • C
    Highly stable
  • D
    Difficult in roasting process

Solution

Iron pyritc i.c., $\mathrm{FeS}_2$, it is also known as Fool's-Gold. It is not an ideal choice of ore for extraction of iron, becausc it produces polluting sulphur containing gases, c.g. $\mathrm{SO}_2, \mathrm{SO}_3$ etc. though it is thermodynamically feasible, stable and can be uscd in roasting process. Hence, option (a) is the correct answer.

Hence, the correct answer is option: 'A'.
