Feldspar minerals make up over 50% of Earth's crust.

GeologyUsesExampleNomenclatureStructureFormationPropertiesApplicationsProductionAppearanceConstructionArchaeologyOverviewFeldspar is the name of a large group of rock-forming silicate minerals that make up over 50% of Earths crust. [1] They are found in igneous, metamorphic, and sedimentary rocks in all parts of the world. Feldspar minerals have very similar structures, chemical compositions, and physical properties. Common feldspars include orthoclase (KAlSi3O8), albite (NaAlSi3O8), and anorthite (CaAl2Si2O8). To appreciate the importance of feldspar as a rock-forming mineral, lets consider its abundance in Earths crust. Most

About 20 million tonnes of feldspar were produced in 2010, mostly by three countries: Italy (4.7 Mt), Turkey (4.5 Mt), and China (2 Mt). Feldspar is a common raw material used in glassmaking, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber. In glassmaking, alumina from feldspar improves product hardness, durability, and resistance to chemical corrosion. In ceramics, the alkalis in feldspar (calcium oxide, pota

Mica Minerals Education Coalition

DescriptionRelation to MiningUsesMica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity. There are 37 different mica minerals. The most common include: purple lepidolite, black biotite, brown phlogo在mineralseducationcoalition.org上查看更多信息
