Question

Identify the mineral of iron from the following.

• A. Willemite
• B. Calamine
• C. Siderite
• D. Magnesite

Hint:

Remember: Siderite is an iron carbonate ore, while magnetite and hematite are iron oxide ores.

Answer 1

The Correct Option is C

Step 1: Understand the minerals listed.
Different metals occur naturally in the form of specific ores or minerals, which are important sources for their extraction.
Step 2: Analyze each option.
(A) Willemite: It is a zinc silicate mineral, not an iron ore.
(B) Calamine: It is a zinc ore, mainly zinc carbonate or zinc silicate.
(C) Siderite: It is iron carbonate $(FeCO_3)$ and is an important mineral of iron.
(D) Magnesite: It is magnesium carbonate $(MgCO_3)$, not related to iron.
Step 3: Conclusion.
Siderite is the mineral that contains iron and is used as an iron ore.
