Mineral Resource of the Month: Garnet

Garnet, the birthstone for the month of January, has been used as a gemstone for centuries. Garnet necklaces dating from the Bronze Age have been found in graves, and garnet is found among the ornaments adorning the oldest Egyptian mummies. However, garnet’s characteristics, such as its relatively high hardness and chemical inertness, make it ideal for many industrial applications.

Mineral Resource of the Month: Tin

Tin was one of the earliest-known metals. Because of its hardening effect on copper, tin was used in bronze implements as early as 3500 B.C. Bronze, a copper-tin alloy that can be sharpened and is hard enough to retain a cutting edge, was used during the Bronze Age in construction tools as well as weapons for hunting and war. The geographical separation between tin-producing and tin-consuming nations greatly influenced the patterns of early trade routes. Historians think that as early as 1500 B.C., Phoenicians traveled by sea to the Cornwall district of England to obtain tin. The pure metal was not used unalloyed until about 600 B.C.

Mineral Resource of the Month: Potash

Potash is the generic term for a variety of mined and manufactured salts, all of which contain the mineral potassium in a water-soluble form. Together with nitrogen and phosphate, potash is one of three essential plant nutrients. Potash is used in everything from fertilizers to soaps and detergents, glass and ceramics, dyes, explosives and alkaline batteries. Minor amounts are also used in water softening, sidewalk deicing, and as a table salt substitute. About 85 to 90 percent of potash, however, is consumed for agricultural products.

Mineral Resource of the Month: Rare Earth Elements

The rare earths are a group of 17 metallic elements that occur in nature as nonmetallic compounds. Ironically, they’re not at all rare: As a group, they are about as abundant as lead in Earth’s crust. Rare earths earned their name to distinguish them from the alkaline earth elements (like beryllium, calcium and magnesium) that were found in the same deposits where rare earths were first discovered in Scandinavia in the late 1800s.

Mineral Resource of the Month: Gypsum

You may not realize it, but the walls of your office are probably made from a mineral: gypsum. Gypsum is an abundant, evaporite-derived sedimentary mineral with deposits located throughout the world. It is often associated with paleo-environmental lake and marine environments. In its pure form, gypsum consists of calcium sulfate dihydrate, although most crude gypsum naturally occurs in combination with anhydrite, clay, dolomite and/or limestone.
