The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals, called gangue, that will have to .
Mineral Mineral Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (, halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level ...
Iron Iron Compounds: The most important oxidation states of iron are +2 and +3, though a number of +4 and +6 states are known. For the element iron the trends in the relative stabilities of oxidation states among elements of the first transition series are continued, except that there is no compound or chemically important circumstance in which the oxidation state of iron is equal to the ...

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturallyoccurring minerals on Earth. Naturallymagnetized pieces of magnetite, called lodestone, will attract small pieces ...

(Iron ore, hardwood trees, limestone and water) Iron ore is a rock that contains a certain amount of iron but mixed with various silicates and oxygen atoms. In 1792 Centre Furnace began manufacturing iron by filling the 35 foot furnace stack with charcoal and sending a blast of air through the furnace with use of bellows powered by a water wheel.
The study aimed at investigating the chemical composition and microstructure of raw iron ore from the deposits in Muko area (southwestern Uganda). The quality of this iron ore was evaluated to establish its suitability to serve as a raw material for iron production. Samples were taken from the six hills of Muko ore deposits and tests carried out to establish their composition and properties.

CaO now reacts the impurities of ore called GANGUE to form slag. Slag is the mixture of CaSiO 3 and Ca(AlO 2) 2. The slag floats over the top of molten iron. Slag is a useful byproduct. It is used in road making, cement manufacturing a light weight building materials.
The world''s resources are dominated by lowgrade ore, though current world production of iron ore is largely by supply from deposits of highgrade ore composed of either rocks of massive hematite or pisolitic goethite. World iron ore production in 2013 was billion tonne, with the major producers being China, Australia, and Brazil.
Chemical formula Description; Ore mineral: Hematite: Fe 2 O 3: Iron oxide: Magnetite: Fe 3 O 4: Primary iron oxide: Goethite: FeOOH: Most abundant iron oxyhydroxide with three subtypes: yellow ochreous has excess water and chemical impurities; brown, the most common variant, is stoichiometric; while vitreous is glassy and contains 2–9% SiO 2 + Al 2 O 3, either as an impurity or as submicron ...
Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first separated from the gangue and then converted to pure iron.
What is the chemical formula for iron ore? Ores: Ores are rocks that contain enough of a mineral for the extraction of that mineral to be economically viable. The decision of whether a rock can be ...
Iron Ore Formation. Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times highgrade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without ...
