Industrial resources (minerals) are geological materials that are mined for their commercial value, which are not fuel (fuel minerals or mineral fuels) and are not sources of metals (metallic minerals) but are used in the industries based on their physical and/or chemical properties.They are used in their natural state or after beneficiation either as raw materials or as additives in a wide range of applications.

👉 Industrial minerals in the context of Perlite
Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. It is an industrial mineral, suitable "as ceramic flux to lower the sintering temperature", and a commercial product useful for its low density after processing.

Industrial minerals in the context of West River (South Dakota)
West River is the portion of the state of South Dakota located west of the Missouri River; it contains more than one-half of the land area and between one-quarter and one-third of the population of the state.
The contrast between the two regions is striking. While East River is predominantly a corn- and wheat-growing region, with large numbers of pigs and poultry operations, West River is predominantly ranching with some dryland farming. Population has decreased as family farms declined due to the harsh conditions and industrialization of agriculture. Other than aggregates, all mining in South Dakota (including gold and other precious metals, industrial minerals, iron ore, and coal) is located in West River, which includes the Black Hills. Both areas were occupied for thousands of years by varying cultures of indigenous peoples. The Great Plains tribes, especially the Lakota or Sioux groups, held most of the territory west of the river. West River includes the Badlands, a vast expanse of rugged, unusable land designated a national park in 1939.
