Iron Ore - Department for Energy and Mining

What is iron ore? 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.

Why is hematite used over magnetite? Magnetite has more ...

Magnetite is a form of iron oxide, Fe 3 O 4, which possesses uniquely iron in both the Fe 2+ and Fe 3+ oxidation states. Bearing the form of an inverse spinel, it's magnetic properties are highly valued. Addition of magnetite to soil is advantageous as it can later be removed easily by using magnets. It can occur naturally in soil, or be added as a soil treatment agent.

Magnetite Hematite Iron Ore Flow Process

The major rock types mined for the production of metallic iron are massive hematite, pisolitic goethite/limonite, which provide a 'high-grade' ore, and banded metasedimentary ironstone, magnetite-rich metasomatite, to a much lesser degree, rocks rich in siderite, rocks rich in chamosite which provide a 'low-grade' ore.
