Question

Which of the following is an iron ore?

Options

• cinnabar

• calamine

• haematite

• rock salt

Answer 1

Haematite

Explanation:

Haematite is the primary oxide mineral used to extract iron, and it primarily consists of iron (III) oxide (Fe₂O₃). The other options are incorrect because cinnabar is the primary ore for mercury, calamine is a common ore for zinc, and rock salt is a natural source of sodium.
