Hematite A primary ore of iron and a pigment mineral

Uses of Hematite (Iron Ore) Hematite is the worlds most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.

What is Iron Ore? Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides hematite (Fe2O3) and magnetite (Fe3O4). These iron ores have been mined to produce almost every iron and steel object that we use today from

How is iron ore formed Answers

Common iron ore minerals include hematite, magnetite, limonite, and siderite. These are frequently found together with assorted silicates. Although iron does not occur in its pure form in nature, some kinds of iron ore contain up to 70% iron atoms. Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind.

Where does iron ore come from? And how its created?

Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores. The most primitive facility used to smelt iron is a bloomery. There, a blacksmith burns charcoal with iron ore and a good supply of oxygen (provided by a bellows or blower). Charcoal is essentially pure carbon.

Transformation of magnetite to hematite and its influence

The high fugacity of oxygen in the fluid phase promotes the reaction of Fe 2+ (in solution) with oxygen. Fe 2+ ions oxidize to Fe 3+ and precipitate as hematite platelets with their longest axes oriented parallel to the direction of maximum stretching. The transformation of magnetite to hematite during deformation plays an important role in the fabric evolution of the iron formation rocks.
