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.

Magnetite Mineral Information photos and Facts, Iron Ore

Magnetite is easily recognized by its color, magnetism, and hardness (6). The mineral is infusible before the blowpipe. Its powder dissolves slowly in HC1, and the solution reacts for ferrous and ferric iron. Strongly magnetic; sometimes exhibits polarity and is therefore a natural magnet, known as lodestone.

Iron. Ferruginous rock containing one or more minerals from which metallic iron may be profitably extracted. The chief ores of iron consist mainly of the oxides: hematite, Fe2O3 ; goethite, alpha -FeO (OH); magnetite, Fe3O4; and the carbonate, siderite FeCO3.

The following is an introduction to these four types of iron ore, magnetite, hematite, limonite and siderite. Iron ore property. Iron is widely distributed in nature (the crust), but since iron is easily combined with other elements to form various iron minerals (compounds), there is little natural pure iron in the earth's crust.

Iron Ore | Geoscience Australia

The Brockman Iron Formation in this province is the most significant host for high-grade hematite iron ore deposits. Magnetite is an iron oxide mineral that is generally black and highly magnetic.

Why we use hematite over magnetite as iron ore? - Quora

Answer (1 of 5): The structure of hematite is hexagonal and that of magnetite is BCT or inverse spinel. During reduction, the phase change in hematite takes place at a temperature of 500 deg C. This change brings with it an increase in the volume thereby increasing the porosity and increased indi...

Based on the ore characteristics (e.g. particle size, mineralogy and grade), gravity concentration (jig and Humphreys spiral), magnetic separation (low and high-field) and inverse cationic flotation (especially applied to pellet feeds) are used [3], [4]. It is estimated that for each tonne of beneficiated iron ore, 400 kg of tailings are produced.

Iron Ore Statistics and Information - USGS

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.
