Iron ore market survey!!

1. ABCM Market Survey
IRON
ORES

3. FERROUS METALS ARE THOSE
WHICH CONTAIN IRON, WHILST
NON FERROUS METALS DON’T
HAVE ANY IRON CONTENT.

4. Metals used for architectural purposes
Lead uses
Tin uses
Steel uses

5. Iron ore
Sedimentary rocks
Iron ore deposits
Iron + oxygen (in marine or fresh water)
Hematite (Fe2O3) Magnetite (Fe3O4)
These iron ores have been mined to produce almost every iron and
steel object that we use today

6. Manufacturing of
Iron ores

8. Iron
• Forms of iron :
Wrought iron
Cast iron
Steel alloy

9. PIG IRON
• High carbon content, typically 3.5–4.5%
• Very brittle, soft, ductile, magnetic
• Has high elasticity and tensile stress
• Made by smelting iron ore

11. Wrought iron
• Purest form of iron
• Characterized by fibrous appearance
• Highly malleable, softer and more ductile
compared to cast iron
• High tensile strength, high resistance to
fatigue

12. CAST IRON
• Cast iron is a group of iron-carbon alloy with a carbon content
greater than 2%.
• Cast iron is made by re-melting pig iron, often along with
substantial quantities of iron, steel, limestone, carbon (coke)
and taking various steps to remove undesirable
contaminants.
• It is more often melted in electric induction furnaces or
electric arc furnaces. After melting is complete, the molten
cast iron is poured into a holding furnace or ladle.
