2020-7-27 · Tantalum-Niobium Separating Beneficiation Plant. Tantalum and niobium are rare metals of high melting point with their good natures like great ductility, low vapor pressure, strong corrosion resistance and big thermal conductivity. They are widely used in industries of electron, atomaic energy, astronavigation, steel, and chemical.
Tantalum is extensively used in the electronics industry, especially in cell phones and laptops while niobium is used mainly in the production of super metal alloys for the use in the construction industry. The presence of U and Th in these Nb/Ta containing minerals (NORMs) however complicates the beneficiation process of the minerals immensely.
