The Boom: Iron ore and Australia - The Conversation

What is iron ore? Iron is found in three major types of iron-bearing minerals – hematite, goethite and magnetite. In general, steel mills love hematite and goethite ores since they contain high grade iron (more than 50% iron), while magnetite ores have lower grades and require more processing to produce a saleable iron ore pellet for the steel mills.

Electron transfer to iron(III) oxides creates iron(II) sites in the mineral. But the iron(II) site is not fixed, as the electron can hop to other sites. Because iron(II) is more soluble than iron(III), when an electron hops to an iron atom at the mineral surface, that iron(II) atom can be released into solution, and dramatically affect the chemistry and mineralogy of …
