PRODUCTION OF NIOBIUM AND TANTALUM

Niobium sources (ores and crude commercial products) usually contain tantalum and chemical extraction processes, therefore, yield niobium with an appreciable tantalum content. Extracting niobium and tantalum by heating with potassium hydroxide and then separating potassium niobate and potassium tantalate from insoluble matter results in considerably less niobium and tantalum than are present in

Niobium and tantalum - USGS

Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties. Their properties of hardness, conductivity, and resistance to corrosion largely determine their primary uses today. The leading use of niobium (about 75 percent) is in the production of ...
