Stiffness: When an external force is applied on a metal, it develops an internal resistance. The internal resistance developed per unit area is called stress. Stiffness is the ability of a metal to resist deformation under stress.

Iron ore is, usually, found in the form of
1. As oxides (Haematite, Magnetite, Limonite)
2. As Carbonates ( Siderite)
3. As sulphides (Pyrite)
The iron ore mostly used for the production of pig iron is hematite.
The principal iron ores are hematite (Fe2O3) .
Hematite is an iron oxide mineral.
Hematite contains iron about 70%

Smelting is the process of reducing the ore with carbon in the presence of flux.
