Classification and Nomenclature of Minerals
Classification. Just as sulfur and chromium form the anion groups (SO4)2- and (CrO4)2-, the ions of molybdenum (Mo) and tungsten (W) bond with oxygen atoms to create the anion groups (MoO4)2- and (WO4)2-. These anion groups then bond with metal cations to form the minerals of the. molybdate and tungstate classes.

2.6: Classes of Minerals
Except for the native element class, the chemical basis for classifying minerals is the anion, the negatively charged ion that usually shows up at the end of the chemical formula of the mineral. For example, the sulfides are based on the sufur ion, S 2–. Pyrite, for example, FeS 2, is a sulfide mineral.

2.2.4 During 20th Century. The world's most regarded economic geologist, Waldemar Lindgren (1860 – 1939) (Fig. 2.3b) (one of the founders of modern economic geology) in 1911, wrote a book 'Mineral Deposits'. He classified mineral deposits into two types such as Pyrometasomatic and Hydrothermal Deposits.
Iron (Fe) Ore | Minerals, Occurrence » Geology Science
Composition: Iron ore is primarily composed of iron, usually in the form of iron oxides such as hematite (Fe2O3), magnetite (Fe3O4), or goethite (FeO (OH)). It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements. Physical properties: Iron ore is usually hard, dense, and heavy.
