Question

The important oxide ore of iron is

• A. Siderite
• B. Haematite
• C. Pyrite
• D. Bauxite

Hint:

Remember: Haematite = Fe\(_2\)O\(_3\) (oxide), Siderite = FeCO\(_3\) (carbonate), Pyrite = FeS\(_2\) (sulphide).

Answer 1

The Correct Option is B

Step 1: Identify iron ores.
Major iron ores: Haematite (Fe\(_2\)O\(_3\)), Magnetite (Fe\(_3\)O\(_4\)), Limonite, Siderite (FeCO\(_3\)).
Step 2: Choose oxide ore.
Among the options, Haematite is the oxide (Fe\(_2\)O\(_3\)) and a principal commercial ore of iron.
Step 3: Eliminate others.
Siderite is a carbonate; Pyrite is sulphide (FeS\(_2\)); Bauxite is an aluminium ore.
Step 4: Conclusion.
Hence, the correct answer is (B) Haematite.
