Q. Which Jharkhand district has rich copper ore reserves?
Answer: East Singhbhum
Notes: East Singhbhum district in Jharkhand contains the Singhbhum Copper Belt with major deposits like Mosaboni and Rakha. Hindustan Copper Ltd operates the Indian Copper Complex at Ghatsila here since 2018-19. Jharkhand is the third largest copper producer in India, contributing about 19% nationally. Other districts like Palamu and Ranchi lack significant copper deposits and focus on minerals such as graphite, bauxite, and coal. Hazaribagh has copper reserves but currently no active production.
