Name the famous gold mines in India.

Answer 1

Hint:
 In India, there are three gold areas mainly. Here are - Kolar Goldfield in Kolar district of Karnataka, Hutt Goldfield in Raichur district of Karnataka and Ramagiri Goldfield in Anantapur district of Andhra Pradesh.

Complete answer:
This is a valuable metal, which is in Orefire loads and some of these rivers are found in the sand. It is used to make ornaments and it is known as international currency due to universal use.

Karnataka is the largest producer of gold in India. The state has reserves of seventeen million tonnes of gold ore of fourth two kilogram of metal, in the main in Kolar, Dharwad, Hassan and Raichur districts. Gulbarga, Belgaum, Bellary, Mysore, Mandya, Chikmagalur and Shimoga districts are also reported to have some gold reserves from some scattered areas. This state produced about 88.7 percent of India's gold.

Deposits in the Kolar Gold Fields occur in an 80 km long (north-south) and 3–4 km wide belt with gold-bearing quartz veins confined to a 6 –7 km section near Marikuppam. The primary mining operations at the Kolar Gold Fields began in 1871 and therefore the region still remains the biggest provider of gold in Asian countries.

The main problem with Hatti mines is the low grade of ore. The mine reopened in 1948 and has been operational on an irregularly basic basis since then. The healthy gold reserves of gold farms in Raichur district are estimated at 4.5 million tonnes, with a total gold content of about 45,000 kg.

Note:
Some gold is collected from the sand and gravel of e rivers. Gold is often released from rocks by weathering and its particles are concentrated at some places in rivers. Such deposits are units referred to as alluvium deposits from that gold is recovered by panning. Although in very small quantities, this type of gold is widely spread in large numbers of rivers.
