Copper is widely used in various applications, …

Ore is a deposit of one or more precious minerals in the Earth's crust. The most important ore deposits, such as copper, silver, and iron, contain metals that are essential to industry and trade. Copper ore is mined for a wide range of industrial applications. Copper, an exceptional electricity conductor, is used as an electrical wire.

Bauxite is formed when aluminosilicates break down into different types of hydrated aluminium oxide. It is the main ore of aluminium. The rock is produced due to chemical weathering in tropical climates. It is also produced by leaching of silica in aluminium-bearing rocks. The aluminium rock was discovered by French geologist Pierre Berthier.

The mineral olivine has the chemical formula (Mg,Fe) 2 SiO 4, in which one silicon and four oxygen atoms are bonded with two atoms of either magnesium or iron.

Broadly, iron's compounds can be divided into two groups known as ferrous and ferric (the old names) or iron (II) and iron (III); you can always substitute "iron (II)" for "ferrous" and "iron (III)" for "ferric" in …

Iron, which takes its English name from the old Anglo-Saxon and its symbol from the Latin, ferrum, was identified and used in prehistoric times. It is a very common element, fourth most abundant in the earth's crust. In addition, two of the ten most common compounds in the earth's crust are the two common oxides of iron, (FeO) and …

Goethite is related to limonite and bog iron (see below), and it was not before 1806 that it was recognized as a mineral in its own right. To honor Goethe, some dignities suggested to name the "new" mineral after him, and there is a certain irony in the fact that the freshly found specimens were quite likely not what goes for Goethite today but "Lepidokrokit" …

Chemically, mica is a complex silicate with a general formula of AB2–3(X, Si)4O10(O, F, OH)2. Its composition is variable, with the potential for substitution by metals such as potassium ...

Some people write its main chemical formula as m Fe2O3nH2O. It appears earth-yellow or brown, containing about 62% Fe, 27% O, and 11% H2O, with …

Iron is one of the three naturally magnetic elements; the others are cobalt and nickel. Iron is the most magnetic of the three. The principle ores of iron are hematite (70% iron) and magnetite (72% iron). Taconite is a low …

Lithium (Li) ore is a type of rock or mineral that contains significant concentrations of lithium, a soft, silver-white alkali metal with the atomic number 3 and symbol Li on the periodic table. Lithium is known for its unique properties, such as being the lightest metal, having the highest electrochemical potential, and being highly reactive …

The chemical formula of a compound is a symbolic representation of its chemical composition. Chemical formulae provide insight into the elements that constitute the molecules of a compound and also the ratio in which the atoms of these elements combine to form such molecules.

Rust is mostly made up of two different iron oxides that generally vary in the oxidation state of the iron atom. These oxides are: Iron(II) oxide or ferrous oxide. The oxidation state of iron in this compound is +2 and its chemical formula is FeO. Iron(III) oxide or ferric oxide, where the iron atom exhibits an oxidation state of +3.

For a blast furnace, iron ore and coke (coal that has been treated to remove volatile components) are added to the furnace, which is fired by air. Lime is also added to reduce the iron from the ore to its metallic form. This produces so-called pig iron, which is then sent to a direct oxygen furnace for the production of molten steel.
