	Silmet
	http://www.silmetgroup.com/ Based in Estonia, Silmet produces many tantalum products including tantalum hydroxide, tantalum oxide and tantalum metal ingots. One of the biggest rare metal and rare earth metal producers in Europe - Silmet - has been operating on the Southern Coast of the Gulf of Finland for over a half a century. In 1928, an oil chemical plant was founded here to process oil shale, a local raw material. After World War II, Estonia was occupied by Soviet troops and Silmet became an important military industrial facility for the former Soviet Union. Instead of oil shale, Silmet began processing uranium since 1946. Initially, local uranium ore was used as raw material. As the uranium content of the local ore is rather low, the plant switched later to imports from Eastern Germany and Hungary. In 1970, processing of Rare Metals and Rare Earths was started. First, Loparite from Kola Peninsula was used as raw material, and now the plant is using RE Concentrates imported from Russia. In 1990, processing of radioactive materials was abandoned altogether and the facilities decontaminated. In 1991, Estonia restored its status as an independent nation. Silmet was restructured and fully privatized in 1997.
