Iron | Geoscience Australia
The minerals that are mostly used as ore for making iron are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Iron is quite soft and easily worked, but it has a very high melting point of 1538°C. Iron and some alloys of iron are also magnetic. Iron is about eight times heavier than water (its relative density is 7.87).
