Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.

The vast majority of the magnetic particles used are based on the iron oxides, magnetite (Fe 3 O 4) and maghemite (γ-Fe 2 O 3). Maghemite is isostructural to magnetite with a cation deficient site and it is generally produced by oxidating the latter with ferric nitrate (Bee et al., 1995) or by exposing it to air (Sun et al., 2004).
