Karnataka is a mineral-rich state in India, and its diverse resources play a significant role in supporting local industries, particularly iron and steel manufacturing and heavy engineering.12

Key mineral resources include:

Iron Ore: The state possesses high-grade reserves, most notably in the Bellary district and the Baba Budan hills, which feed regional steel mills.13
Chromite and Magnesite: Karnataka is a major producer of chromite and is one of the few Indian states that produces magnesite.1
Other Minerals: The state also extracts manganese, bauxite, copper ore, mica, and garnet.13

Historically, the Kolar Gold Fields were vital to the economy, producing the vast majority of India’s gold during the 20th century. However, due to the depletion of deposits and high operating costs, these mines were closed in 2001.14
