The correct Answer is:
To answer the question "An important ore of iron is," we will analyze the information provided in the video transcript and identify the key ores of iron. ### Step-by-Step Solution: 1. **Understanding Ores**: Ores are naturally occurring minerals from which metals can be extracted profitably. For iron, there are several important ores. 2. **Identifying Iron Ores**: The video mentions three important ores of iron: - **Pyrite (FeS2)**: This is iron disulfide, but it is not primarily used for iron extraction. - **Hematite (Fe2O3)**: This is one of the most important ores of iron and is widely used for iron extraction. - **Siderite (FeCO3)**: This is another ore of iron, but less commonly used compared to hematite. 3. **Conclusion**: Among the ores mentioned, Hematite (Fe2O3) is the most significant and widely used ore for extracting iron. Therefore, the answer to the question is Hematite. ### Final Answer: An important ore of iron is **Hematite (Fe2O3)**. ---
