Hollandite is an ore mineral of which one of the following elements?
- Fe
- Mn
- Pt
- Cr
The Correct Option is B
Solution and Explanation
To answer the question of which element is associated with the ore mineral Hollandite, we need to understand the nature and composition of Hollandite.
Hollandite is a mineral known as a manganese oxide. Its chemical formula can be represented as Ba(Mn6Mn2)O16, where Mn stands for Manganese. Hollandite is known for its high concentration of manganese. Therefore, it is categorized as an ore of manganese.
Let's consider the options provided:
- Fe - Represents Iron. Hollandite is not an ore of Iron.
- Mn - Represents Manganese. As discussed, Hollandite is an ore mineral of Manganese.
- Pt - Represents Platinum. Hollandite is not associated with Platinum.
- Cr - Represents Chromium. Chromium is not a component of Hollandite.
Based on the above explanations, the correct answer is that Hollandite is an ore mineral of Manganese (Mn).
Therefore, the correct choice is Mn.
