What are minerals? Discuss different types of minerals on the basis
of their composition in detail.
Answers
Minerals are defined as solid, inorganic, naturally occurring substances with a definite chemical formula and general structure. Almost all chemical elements in the Earth's crust are associated with at least one mineral. They vary in color, hardness, density, crystal form, crystal size, transparency, composition, location, and abundance. Some minerals are radioactive (uranophane), while others are magnetic (magnetite). Some are uncombined elements, such as gold, silver, sulfur, bismuth, copper and platinum. Certain minerals, such as fluorite (calcium fluoride), glow with a vibrant luminescence after exposure to ultraviolet light. Feldspar (a potassium aluminum silicate) and quartz (silicon dioxide) are the most abundant minerals found in the Earth's crust.

Explanation:
Minerals are solid substances found in nature. They are not alive. The atoms which make up a mineral are fitted together to form a crystal. The chemical composition that is the kinds of atoms in a given kind of crystal is the same for every crystal of that kind although impurities or matter that is not part of the crystal may be included. Gold, diamond, rock salt and the graphite used to make the “lead” in pencils are examples of minerals.
Each of these minerals is different yet many times minerals look like one another or something else. A piece of green coloured plastic may look identical to an emerald. A very clear piece of quartz may look like a rough diamond. The Mols hardness test a streak test, colour, luter, cleavage and fracture are all ways of identifying minerals.
Examples:
1. Metallic Minerals
Metallic minerals exhibit lustre in their appearance and consist of metals in their chemical composition. These minerals serve as a potential source of metal and can be extracted through mining. Examples of metallic minerals are Manganese, iron ore and bauxite are Metallic minerals and be divided into ferrous and non-ferrous metallic minerals.
Ferrous minerals are one that contains iron and non-ferrous are one that does not contain iron.
2. Non-metallic minerals
Non-metallic minerals are minerals which either show a non-metallic lustre or shine in their appearance. Extractable metals are not present in their chemical composition. Limestone, gypsum, and mica are examples of non-metallic minerals.
Bauxite ore mostly exists in deeply weathered rocks. Volcanic rocks contain bauxite deposits in some regions.
Iron metal extracted from iron ore. It never exists in pure form and has to be extracted from iron ore by eliminating the impurities.
Gold is the oldest and most precious element to be known.
Manganese ore is a silvery brittle or grey-white metallic ore occurs in many forms and found worldwide.
