Following is a list of minerals that serve as copper ores in the copper mining process: [1] Image Name Formula % Copper when pure Chalcopyrite: CuFeS 2: 34.5 Chalcocite:
In 2022, the Archaeological Survey of India found copper anthropomorphic figures and weapons that could potentially date back to 1600 to 2000 BC. [56] Details of copper mining and metallurgy are available in ancient works like the Arthashastra. [57] In India, consumers of copper include the real estate, home appliance manufacturing and ...
This lists of mines in India is subsidiary to the list of mines article, and future mines in the country and is organised by the primary mineral output. For practical purposes stone, marbles and other quarries may be included in this list. In India, the underground mine to surface mine ratio is 20:80 [citation needed].
Use of copper in ancient India in making of idols such as dancing or Tandava Shiva. Copper production in India is only about 2 percent of world copper production in view of its potential reserve limited to 60,000 km 2 (2% of world reserve) of which 20,000 km 2 area has been subject to exploration, as of 2012.

The metallic minerals comprise ferrous and non-ferrous minerals, while the nonmetallic minerals comprise mineral fuels, precious stones, among others. [ 4 ] D.R. Khullar holds that mining in India depends on over 3,100 mines , out of which over 550 are fuel mines, over 560 are mines for metals, and over 1970 are mines for extraction of ...
KALIAPANI, India (AP) — In the dusty mountains of eastern India, workers at the country's largest chromium deposit have mined for the essential ore, rain or shine, for around 60 years.
Production trends in the top five copper-producing countries, 1950-2012. This is a list of countries by mined copper production. Copper ore can be exported to be smelted so that a nation's smelter production of copper can differ greatly from its mined production. See: List of countries by copper smelter production.
Ore minerals in IOCG deposits are typically copper-iron sulfide chalcopyrite and gangue pyrite, forming 10–15% of the rock mass. Supergene profiles can be developed above weathered examples of IOCG deposits, as exemplified by the Sossego deposit, Para State, Brazil , where typical oxidised copper minerals are present, e.g.; malachite ...
