Mineral Resources Flashcards
Definition of Minerals
Natural substances of organic or inorganic origin
with definite chemical and physical properties
Minerals are broadly classifies on the basis of?
Physical and Chemical properties.
Metallic and Non-metallic minerals.
Definition of metallic minerals
They are the source of metals like iron, copper, gold etc.
Metallic minerals are further categorized as
Ferrous and non-ferrous minerals
Ferrous minerals have
iron content like iron ore
Non-ferrous minerals
Do not have iron content like copper, bauxite etc.
Non-metallic minerals are either
Organic or inorganic in origin
Organic non-metallic minerals include
Inorganic non-metallic minerals include
Fossil fuels or Mineral fuels like coal and petroleum -> Derived from the buried plant and animal life .
Mica, Limestone, graphite -> Inorganic
What are the unique characterastics of minerals:
- Their distribution over space is not even
- Inverse relationship in quality and quantity
- Minerals are exhaustible => Take long time to geologically develop, cannot be replenished immediately when needed. No second crop.
Minerals forms the base for several ___-scale industries.
Agriculture is influenced by minerlas in the form of __-.
This devlopement of a country is influenced by minerals
Large
Fertilizers
Economic
3 points which says the importance of minerals
- Econmic devlopment
- Basis of large scale industry
- Agriculture -> Fertilizers
Why does India have rich variety of minerals?
And why is it said to be “rich”?
- Due to its vaired geological structure.
- Rich -> Considerable importance by world standards
- Ranking fairly high among Iron, Coal Mica and manganese (MICoM)
- Extensive reservfes of chromite, bauxite and limestone
Give examples of ferrous minerals:
- Iron ore
2. Manganese
Points on richness of india of iron ore:
- Faily rich in iron deposits.
- Some amount of iron is found in practically all parts of the country
- Largest producer of Iron in asia and one of the largest in world
Rough distribution of Iron ore in India:
- Occur as hill masses and are easily accessible
2. They are found in close proximity to areas producing coal, dolomite, limestone and manganese. (CD, LM)
Why is there an adantage in iron and steel plant in utilisation of resources?
They are found in close proximity to areas producing coal, dolomite, limestone and manganese. (CD, LM)
Types of Iron ore with their percentage:
- Haematite -> 60 to 70%
- Magnetitie -> 70%
- Limonite -> 35 to 50%
Give 3 points about haematite:
- Reddish in colour and is known as red ore
- Contains 60 to 70% of iron
- Found in Odisha, jharkjand, chattisgarh (central east region)
Give 3 points about magnetitie:
- Dark brown to blackish in color, also known as black ore
- Best quality more than 70% and has magnetic property
- Found in TN and Karnataka (Southern)
Why is magnetite called magnetite?
It possesses magnetic property
Give 3 points about limonite:
- It is yellow or light brown in color and contains 35 to 50% of iron.
- 35 to 50% of iron (poorest)
- Iron stone group -> Raniganj. Mirzapur(UP), Gharwal and Kangra valley

Uses of iron ore:
Just points
- Iron ore: To use steel
- Powdered steel: Metallurgy products (magnets), Catalyst, Auto parts
- Iron Blue: 4 Ps (Paints, Plastics, Paper dyeing, Printing inks), 2Cs (Colors for artists, Cosmetics), Industrial finishes
- Radioactive iron (59%) -> Medicine (tracer element), Biochemical and Metallugical research
- Black iron oxide -> 3Ms (Metallurgy, magnetic inks, medicine)
Give the use of iron ore in making of steel:
- 90% Iron ore is used to make steel.
- Raw iron is not strong and hard
- Alloyed with other elements to make it strong and hard.
The major states of iron ore:
The middle east:
- Jharkand
- Chattisgarh
- Odisha
The South:
- Tamil Nadu
- Karnataka
- Andhra pradesh
The west:
- Rajasthan
- Maharastra
- Goa
