  • Mineral - Classification of minerals Britannica

    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 (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level ...

    OverviewMineral resourcesMineral reserves and ore reservesSee alsoExternal links

    Mineral resource classification is the classification of mineral resources based on an increasing level of geological knowledge and confidence. In an effort to achieve a standard set the classifications, representative bodies from Australia, Canada, South Africa, the USA and the UK reached a provisional agreement in 1997 on the definitions of each of the various mineral classifications. This was followed in 1998 to have these definitions incorporated into the International Framework Classification for Reserve

    Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains. The value of the metals or minerals an ore contains must be weighed against the cost of extraction to determine whether it is of su

    The Berzelian mineral classification system was named in honor of the Swedish chemist and mineralogist Jons Jakob Berzelius (1779-1848). The Berzelian system categorizes mineral species according to the main anion group present in their chemical structure. All mineral species of a certain class are therefore chemically similar because they possess the same main anion group. Mineral
