Q. Which is the largest iron ore mine in Jharkhand?
Answer: Chiria
Notes: Chiria iron ore mine in Jharkhand contains the largest iron ore reserves in India, estimated at 2,000 million tonnes. It is considered the biggest iron ore mine in Asia based on reserves. Noamundi iron ore mine has significant production but smaller reserves compared to Chiria. Jharia is known for coal mining, and Jadugoda is a uranium mine, not an iron ore mine. The Indian Bureau of Mines provides data confirming Chiria's reserve status.
