TANTALITE Iron Manganese Tantalum Niobium Oxide

Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non-reactive and non-irritating to body tissues.

History of Columbium Niobium. Niobium, discovered in 1801 by C. Hatchett, an English Chemist in an ore called columbite, is a metal that is closely related to tantalum. It was originally thought that the material was chromium but upon analysis it was determined it was not chromium but an oxide of an unknown element.

niobium processing | History, Ores, Mining,

2 Low-tantalum tin slags, on the other hand, are first melted in an electric-arc furnace with the addition of a flux material, and the tantalum-niobium content is collected as a ferroalloy. The tantalum-rich ore or ferroalloy is then crushed, ground, and decomposed in hydrofluoric acid.
