Real KGF History. Kolar Gold Fields (K.G.F.) is a gold mining region. Over a century, the town has been known for gold mining. Many Tamils live here, in KGF, Karnataka. The mine closed on 28 February 2001 due to a fall in gold prices, despite gold still being present there. One of India's first power-generation units was built in 1889 to support mining operations. The mine complex hosted some particle physics experiments between the 1960s and 1992.
