Ferrous minerals :

  • They account for about 3/4th of total value of production of metallic minerals.
  • They provide a strong base for development of metallurgical industries.
  • India is also an exporter of ferrous minerals.

IRON ORE :

  • Is the basic mineral and backbone of industrial development.
  • India has abundant resources of iron ore.
  • Magnetite is the finest iron ore with a very high content of iron upto 70%.
  • It has excellent magnetic qualities, valuable in the electric industry.
  • Hematite is the most important iron ore in terms of quantity used.
  • It has a lower iron content than magnetite , 50-60%. 
  • In 2018–19 almost the entire production of iron ore (97%) accrued from Odisha, Chhattisgarh, Karnataka, and Jharkhand. The remaining production (3%) was from other states. 

MAJOR IRON ORE BELTS IN INDIA :

Odisha jharkhand belt :

  • In Odisha, high grade hematite ore is found in Badampahar mines in Mayurbhanj and Kendujhar districts.
  • In Singhbhum district of Jharkhand, hematite iron ore is mined in Gua and Naomandi.

Durg Bastar chandrapur belt :

  • Lies in chhattisgarh and Maharashtra.
  • Very high grade hematites are found in famous of Bailadila range of hills in the Bastar district of Chhattisgarh.
  • Range of hills comprise of 14 deposits of super high grade hematite iron ore.
  • It has best physical properties for making steel.
  • Iron ore from these mines is exported to Japan and South Korea via vishakhapatnam port.

Ballari Chitradurga Chikkamagaluru Tumakuru belt :

  • This belt is in karnataka and has large reserves of iron ore .
  • Kudremukh mines located in western ghats of Karanataka are a 100% export unit.
  • Kudremukh deposits are known to be one of the largest in the world.
  • The ore is transported as slurry through a pipeline to a port near Mangaluru.

Maharashtra Goa belt :

  • Includes the state of Goa and Ratnagiri district of Maharashtra.
  • Though, the ores are not of very high quality, yet they are efficiently expoited.
  • Iron ore is exported through Marmagao port.

Manganese :

  • Mainly used in the manufacturing of steel and ferro manganese alloy.
  • Nearly 10kg of manganese is required to manufacture 1 tonne of steel.
  • It is also used in manufacturing bleaching powder, insecticides and paints.
