Minerals Found in Tanzania


Diamond is an extremely hard, highly refractive crystalline form of carbon that is usually colorless and is used as a gemstone and in abrasives, cutting tools, and other applications.

Commercial diamonds mining in Tanzania began in 1940 following the discovery of the Mwadui Kimberlite pipe. Currently, diamonds are mainly mined in the following places: Maganzo, Mabuki, Nyang’wale and Tunduru.

The primary use of diamond is as a hard object—the hardest mineral known, which makes it ideal for industrial use (making cutting, drilling, grinding and polishing tools). Diamonds are also used in jewelery as gemstones; and in electronics to transfer heat away from heat sensitive micro-electronic parts within electronic devices and as friction-resistant micro-bearings in watches.
