Iron Absorption - Bodytomy
Iron absorption is an important function that is fulfilled by the human body, and hence, it is important that one gets to know the process by which iron gets absorbed. The reason why iron is given added importance in the functioning of the human body is because of its integral part in the respiratory system.

Iron ore - Wikipedia
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...
