2. Manganese
• Manganese is a chemical element with symbol Mn and atomic number 25.
• It is not found as a free element in nature; it is often found in combination
with iron, and in many minerals.
• Manganese is a metal with important industrial metal alloy uses, particularly
in stainless steels.

5. Uses of Manganese
• Manganese is used most commonly in steel production to help improve
strength, durability, and toughness.
• It can be used in medicine to help support the immune system, regulate your
blood sugar, and maintain bone regulation and reproduction.
• It is also used in gasoline to reduce engine knock, and is used in alkaline
batteries.

6. Distribution of Manganese
• Manganese is an important mineral, which is used for making iron and steel and it
acts as basic raw material for manufacturing its alloy.
• Nearly 10 kilograms of manganese is required for manufacturing one tone of steel.
• It is also used for the manufacture of bleaching powder, insecticides, paints,
batteries and china-clay .
• According to Geological Survey of India, our total manganese reserves are
estimated at 16.7 crores tones.
• India has the second largest manganese ore reserves in the world after Zimbabwe.

7. Eco-Significance of Manganese
• Manganese has a great economic significance as its mainly used in the
manufacturing of steel and Ferro magnesia alloy.
• Its also used in manufacturing of bleaching powder, insecticides and paints.
• But, the most important use is to provide hardness to steel.
• Also today Ferro magnesia alloy are very common.
• Magnesia is also available at cheap rates to people and hence is most widely used
metal in rural areas.
• This shows that manganese has a great economic significance.

8. Reserves of Manganese in India
• About three-fourths of Manganese reserves in India are distributed in
Maharashtra and Madhya Pradesh.
• The remaining Manganese is distributed in Rajasthan, Goa, Andhra Pradesh,
Orissa, Karnataka, Gujarat, Tamil Nadu and Jharkhand.

11. Imports & Exports
Import
• India is the 2nd most important consumer of Manganese ore in the world, behind
China. Since China has reduced its buying significantly, having ample material
stocked in its ports, India has gained greater importance in the Manganese ore
global trade and is seen as buyer with increased potential of consumption.
• India’s dependence on Manganese Ore imports has increased as the Manganese Ore
produced in India (apart from MOIL) is of low grade and high Iron content, and
these are not suitable to produce the best quality of Manganese alloys. These
inferior quality of Manganese Ores have to be blended with better variety imported
ores or procured from MOIL domestically.

12. Imports & Exports
Export
• India annually exports about 15 per cent of its total production of
manganese ore. However, there has been gradual decline in the quantity of
export since 1971 on ward.
• In 1960-61 India exported 11.661 lakh tones of manganese ore valued at Rs.
221 million. This reached the record high of 16.36 lakh tones valued at Rs.
140 million but fell down to 2.65 lakh tones and valued at Rs. 595 million in9
2000-01.
