• About 95% of India’s mica is distributed in just three states of Jharkhand, Andhra Pradesh and Rajasthan.
  
• Of the above options, Karnataka is not a producer of mica.
  

Karnataka is the largest producer and accounts for nearly one-fourth of the total iron ore produced in India. In Karnataka production of iron ore has increased by about three times since 1980.

Iron ores are widely distributed in the state, but high grade ore deposits are those of Kemmangundi in Bababudan hills of Chikmagalur district and Sandur and Hospet in Bellary district. Most of the ores are high grade haematite and magnetite. The other important producing districts are Chitradurga, Uttar Kannad, Shimoga, Dharwar and Tumkur.

• A mineral is a solid, naturally occurring combination of inorganic substances. Metallic minerals are minerals which contain one or more metallic elements.
  
• Metallic minerals occur in rare, naturally formed concentrations known as mineral deposits. These deposits can consist of a variety of metallic minerals containing valuable metals such as nickel (pentlandite), copper (chalcopyrite), zinc (sphalerite), lead (galena) and gold (occurs as a native element or as a minor constituent within other minerals) that are used in all aspects of our daily lives.
  
• Metallic minerals must be broken apart and chemically processed to extract the useful metal from the mineral.
  

Magnetite is a mineral and one of the main iron ores. With the chemical formula $$Fe_3O_4$$, it is one of the oxides of iron. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of magnetism. Today it is mined as iron ore.

Energy minerals are used to produce electricity, fuel for transportation, heating for homes and offices and in the manufacture of plastics. Energy minerals include coal, oil, natural gas and uranium.

C.  Maharashtra, Orissa, Andhra Pradesh

As per Ministry of Mines Data, production of iron ore at about 218.64 million tons in 2009-10 registered an increase of 2.67% over the previous year. About 27% of the total production was shared by Public Sector Companies like SAIL (including IISCO), NMDC, etc.

The share of Private Sector was 63% which includes Tata Steel (formerly TISCO) (8%). Almost the entire production of iron ore (96%) accrued from Orissa, Karnataka, Chhattisgarh, Goa and Jharkhand during the year. The remaining 4% production was reported from Andhra Pradesh, Madhya Pradesh, Maharashtra and Rajasthan.
