The Malanjkhand copper mines were discovered in 1956 and began production in 1967. The mines are located in the Satpura Range of mountains, about 200 kilometers from the state capital of Bhopal. The mines are open-pit mines and are operated using a combination of conventional and modern mining techniques.
