Which of the following magnetic impurity is present in Cassiterite ore?
- A \(\mathrm{Fe}_{2} \mathrm{O}_{3}\)
- B \(\mathrm{FeW} \mathrm{O}_{4}\)
- C \(\mathrm{FeO}\)
- D \(\mathrm{Fe}_{3} \mathrm{O}_{4}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{FeW} \mathrm{O}_{4}\)
Step-by-step Solution
Detailed explanation
The magnetic impurity present in cassiterite ore is wolframite \(\left([\mathrm{Fe} / \mathrm{Mn}] \mathrm{W} \mathrm{O}_{4}\right)\),
It contains magnetic impurities of tungstates of iron and managanese and the combination is called as wolfromite.
