Examples of Metal Ores. The term ore is used to refer to a rock that contains minerals such as metals. In general, ores are oxides, sulfides, silicates or "native metals," those found in nature. Oxides and sulfides are called such because the minerals contain oxygen or sulfur, respectively, which has formed a chemical compound with the metal.

Aluminum, chemical element, a lightweight silvery white metal of Group 13 of the periodic table. Aluminum is the most abundant metallic element in Earth's crust and the most widely used nonferrous metal. Aluminum never occurs in the metallic form in nature.

Aluminum. Aluminum is the most abundant metal element in the Earth's crust. Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral.

In its mineral form Bauxite, Aluminum is the most abundant metal in the earth's crust. Bauxite contains one of a variety of hydrated aluminum oxides (gibbsite, boehmite or diaspore), which are often expressed as Al 2 O 3 xH 2 O but are more commonly regarded as impure Al 2 O 3. Bauxite is claylike and earthy, and ranges in color from white to ...

Different Types of Iron Ore. The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite. Hematite is the most important iron ore. The iron content of the pure minerals is as follows:

But this is not the case with more reactive iron or aluminum. Usually iron and aluminum exist as compounds, with oxygen, also known as oxides. Some other mineral or other compound is also present. But the majority is a metal oxide. In conclusion, in most cases, ores are simply metal oxides along with other small amounts of minerals.
