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

Iron Ore: Sedimentary Rock Pictures, Definition &

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 almost every iron and steel object that we use today

In What Rock Formations Can Gold Be Found?

Intrusive rock is formed when molten magma is pushed between layers of existing rock. Intrusive rock is typically very hard and erodes slowly. This allows the surrounding rock to be worn away by wind and water, leaving only the harder rock in place. Heavy particles, such as gold, are likely to accumulate against the harder rock while the lighter materials are more easily moved away.
