Types of Iron Ore: Hematite vs. Magnetite

2016-1-4  Types of iron ore: Hematite. Hematite ore has the chemical formula Fe2O3 and has very high iron content of 70 percent. Its name comes from the Greek word for blood, haima, because of its reddish color. High-grade hematite ore is also often referred to as direct-shipping ore because it is mined and extracted with a fairly simple crushing and

Types of Iron Ore: Hematite vs. Magnetite

Hematite ore has been the primary type of iron ore mined in Australia since the early 1960s. Nearly all of Australia’s iron ore exports are high-grade hematite ore, and the majority of its reserves are located in the Hamersley mountain range of Western Australia because the range sits on a banded iron formation.

Iron ore BHP

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.
