A mineral that contains a useful amount of a particular element is an ore. An ore containing iron is called iron ore, such as magnetite (Fe3O4), and hematite (Fe2O3), which contain 70% iron.

Minerals are classified according to their composition
Someone said, "No. Most minerals have a variety of different colors." but that isn't true. Minerals and rocks can be classified by color, streak, luster, cleavage, hardness, and specific gravity. Hope this helps! By: Fizzycandy10
== An ore would be a rock formation rich enough in particular minerals to be economically excavated and extracted for those particular minerals or elements. The extraction of minerals is not the predominant purpose of coal excavation. The main use of coal is for generation of power through burning. Rather than an ore it is considered a fuel.
yes all of them are minerals.Another AnswerNone of them are minerals: coal, diamonds and graphite are formed from the mineral carbon. There is a class of minerals, according to Wikipedia: "The halide minerals are the group of minerals forming the natural salts."
They are classified based on the structure of their silicate group. Silicate minerals all contain silicon and oxygen.

Relative hardness is the property of minerals that uses the Mohs scale for classification.

Minerals are classified by chemical formula, composition, physical properties, optical properties, and special properties. The Dana Classification System is a chemical classification for minerals, and the Strunz Classification System (chemical-structural) are two systems designed for mineral classification.
Minerals are classified as oxides, sulfides, halides, sulfates, silicates, or carbonates. Some elements are also classified as minerals. There's also a metallic and non-metallic mineral classification.
Mineral resources can be divided into two major categories - Metallic and Nonmetallic. Metallic resources are things like Gold, Silver, Tin, Copper, Lead, Zinc, Iron, Nickel, Chromium, and Aluminum. Nonmetallic resources are things like sand, gravel, gypsum, halite, Uranium, dimension stone
Minerals are classified according to the elements they contain. Other important features for classification purposes include the crystalline structure, hardness and cleavage of the mineral when broken.
Minerals aren't classified because Toby McDonough is more fabulous then you. End of story...or should I say, End of the World ;)
It is important to know how natural fibers are classified. Natural fibers are fibers from plant, animal and minerals. They are classified according to their origin.
Non-silicate minerals do not contain the SiO4 ion. Non-silicate minerals are classified as oxides, sulfides, sulfates, halides, or carbonates. Some elements are also classified as minerals. There's also a metallic and non-metallic mineral classification. See the link below for examples.

Minerals are not classified as metamorphic. The mid-oceanic ridges are generally considered to be areas where new basaltic crust is formed from uprising magma. The basalt is considered an igneous rock in classification.
