How do you mined iron?

Answer 1

Iron is mined by it's ore, which is usually an oxide, like rust.

This is shown by it's red earth characteristic.

There are two types, earth or rocky ore. The rocky ore is heated with coal to remove the oxides via redox reaction, while earth has to be refined before heating.

Rocks are usually blasted by explosives and carted away, while earth ores are dug up by cartloads.
