    Iron ore | BHP

    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. Iron is responsible for the red colour in many of our rocks and the deep red sands of the Australian deserts, and is a key ingredient in steelmaking.

    Why is hematite used over magnetite? Magnetite has more

    Nov 11, 2017· Magnetite has higher iron content than hematite. Buthematite ore usually contains large concentrations of hematite; magnetite ore, low concentrations of magnetite. The ore has lower iron content, typically between 25% and 40% Fe. This ore is unsuitable for steel making, and it must be concentratedbefore it can be used toproduce steel. Magnetite ore’s magnetic properties are helpful …

    Metal Oxides In Soils: The Effects OfHematite And Magnetite

    Like magnetite, hematite is an oxide of iron and it has the formula Fe 2 O 3. Hematite is not magnetic, and so is not readily removed from soils to which it has been added. It also can occur naturally in soil. Hematite is the most prevalent oxide of iron present in the ground, as such, it is also the largest source of iron for iron/steel production.

    IronOre Statistics and Information USGS

    Iron Ore Statistics and Information. 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.

    Jan 31, 2018· It is mainly found in sedimentary rocks. But it is sometimes found in beach sand in large quantities. The major use of magnetite is as a source to extract iron in the form of pig iron or sponge iron form. This produced iron is further used to convert into steel. In addition, magnetite is used as a catalyst.
