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
A metamorphic rock can be classified according to its texture, mineral composition, and metamorphic grade. Texture refers to the size and arrangement of mineral grains, while mineral composition indicates the minerals present. Metamorphic grade refers to the temperature and pressure conditions under which the rock formed.
Milk is a complex mixture of various organic compounds, primarily water, proteins, carbohydrates, fats, minerals, and vitamins. In chemistry, it is classified as an emulsion, which is a mixture of two or more liquids that are normally immiscible (do not mix) - in this case, fat droplets dispersed in water.
Vitamins are organic compounds that the body needs in small amounts for various biochemical functions, while minerals are inorganic elements that the body needs in larger amounts for structural support and physiological processes. Vitamins are classified as water-soluble or fat-soluble, while minerals are classified as major minerals (needed in larger amounts) or trace minerals (needed in smaller amounts).

Relative hardness is the property of minerals that uses the Mohs scale for classification.
Minerals are classified according to their composition
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.
Rocks are classified based on their composition, which includes their mineral content and texture. Color can sometimes provide clues about the minerals present in a rock, but it is not the sole factor used for classification. Other properties such as hardness, visible crystals, and how the rock formed are also important in determining its classification.
The main classification criterion is the chemical composition. 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.
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.
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.

The Dewey Decimal Classification for rocks and minerals falls under the category 550, which is designated for Earth sciences. More specifically, rocks are classified under 552, while minerals are classified under 549. This system helps organize materials in libraries related to geology and related earth sciences.
