Although iron is an essential mineral, much of it is extremely toxic. Free iron in the blood reacts with peroxides to form free radicals that damage DNA, protein, lipids and other cellular components, leading to illness and sometimes death. Twenty milligrams of iron per kilogram of body weight is toxic, while 60 milligrams per kilogram is lethal.
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.
Iron is the third most common element making up the Earth. Iron is one of the three naturally magnetic elements; the others are cobalt and nickel. Iron is the most magnetic of the three. The principle ores of iron are hematite, (70% iron) and magnetite, (72% iron). Taconite is a low-grade iron ore, containing up to 30% magnetite and hematite.
Banded iron formations may contain iron in carbonates (siderite or ankerite) or silicates (minnesotaite, greenalite, or grunerite), but in those mined as iron ores, oxides (magnetite or hematite) are the principal iron mineral. Banded iron formations are known as taconite within North America.
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 (Fe 2 O 3) and magnetite (Fe 3 O 4). These iron ores have been mined to produce ...

Jul 23, 2019· Iron is a mineral that our bodies need for many functions. For example, iron is part of hemoglobin, a protein which carries oxygen from our lungs throughout our bodies. It helps our muscles store and use oxygen. Iron is also part of many other proteins and enzymes.
iron (Fe) [i´ern] a chemical element, atomic number 26, atomic weight 55.847. (See Appendix 6-1.) Iron is chiefly important to the human body because it is the main constituent of hemoglobin, cytochrome, and other components of respiratory enzyme systems. A constant although small intake of iron in food is needed to replace erythrocytes that are ...
Iron is a trace mineral needed to make hemoglobin, the protein needed to carry oxygen throughout the body. Hemoglobin gives red blood cells their color, and stores most of the body's iron supply. Iron is also stored in muscle tissue, and helps supply the muscles with the oxygen needed to make them contract. ...
