Extraction of Iron | Metallurgy Chemistry

It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state.

Tin Wikipedia

Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. Tin is a silvery metal that characteristically has a faint yellow hue. Tin, like indium, is soft enough to be cut without much force. When a bar of tin is bent, the socalled tin cry can be heard as a result of sliding tin crystals reforming; this trait is shared by indium, cadmium, and frozen mercury.
