Kolar gold fields: Besides gold extraction

Besides gold extraction, KGF has been utilized for particle physics experiments, leading to the discovery of atmospheric neutrinos. Currently, India operates three gold mines: Hutti and Uti in Karnataka, and Hirabuddini in Jharkhand. The Kolar Gold Fields (KGF) in Karnataka, once among Asia’s largest and deepest gold mines, produced an estimated 800–900 tonnes of gold over 120 years of continuous operation since the 1880s. Kolar Gold Fields (K.G.F.) is a mining region in K.G.F. taluk (township), Kolar district, Karnataka, India. In a move that blends history with modern mining technology, India is reviving the iconic Kolar Gold Fields (KGF) in Karnataka—its first gold mine restart since independence.
