Tantalum and niobium ore refers to tantalum and niobium minerals. There are more than 100 species. The minerals containing tantalum and niobium are mainly tantalum iron and calcite. Tantalum and niobium iron ore is called tantalum iron ore and niobium iron ore. Among them, it can be used for ore mining, mainly from tantalite, niobium iron ore and calcite. Tantalum (Ta) niobium (Nb) belongs to high melting point (tantalum 2996 ℃, niobium 2468 ℃), high boiling point (tantalum 5427 ℃, niobium 5127 ℃) rare metal, appearance like steel, grayish white luster, powder dark gray, suction, corrosion resistance and superconductivity. Unipolar conductivity and high strength at high temperature . Used for preparation of tantalum oxide, niobium oxide, extraction of tantalum, niobium, etc. Grade analysis can be carried out quickly by special tantalum and niobium ore wave acoustic ore analyzer.

    The iron ore and the pyrochlore can be collected by the cation collecting agent and can also be used as the anion collecting agent. And the flotation effect of the complex collector (such as sodium hydroxamic acid) is better.
