Casseterite ore consists of magnetic impurity named as

Options

A. Chromite
B. Wolframite
C. Magnetite
D. Limonite

Explanation

**Step-by-Step Text Solution:**

1. **Identify the Ore**: The question asks about the cassiterite ore, which is primarily composed of tin dioxide (SnO2).

2. **Identify the Impurity**: The question specifies that cassiterite contains a magnetic impurity.

3. **Name the Magnetic Impurity**: The magnetic impurity found in cassiterite is known as wolframite.

4. **Composition of Wolframite**: Wolframite is a mineral composed of iron, manganese, and tungsten. Its chemical formula is represented as MnWO4.

5. **Nature of Wolframite**: Wolframite is paramagnetic in nature, which means it is attracted to magnetic fields but does not retain magnetism when the external field is removed.

6. **Conclusion**: Therefore, the magnetic impurity present in cassiterite ore is wolframite.

**Final Answer**: The cassiterite ore consists of the magnetic impurity named wolframite.
