Classification of minerals
The classification of minerals is a process of determining to which of several groups minerals belong based on their chemical characteristics. Since the 1950s, this classification has been carried out by the International Mineralogical Association, which classifies minerals into the following broad classes: • Classification of non-silicate mineralsIn geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid substance with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form. The geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or organic compounds in Mineral

Mineral Resources and Reserves SpringerLink
The national standard Classification of Solid Mineral Resources/Reserves (GB/T17766―1999) issued in 1999 divided mineral resources and reserves into reserves, basic reserves, and resources. It can be seen from the development history that before 1990, there were only reserves and no resources in the concept of Los minerales son sólidos: Un sólido puede mantener su forma indefinidamente, y por lo tanto no se ajustará a la forma de su contenedor.Los líquidos (como el aceite o el agua) y los gases (como el Clasificación y Tipos de Minerales [ Esquemas y

Mineral Classification, Properties, Types Britannica
Mineral Classification, Properties, Types: 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).
