        The content of tantalum in tantalum-niobium ore is as high as 60%. Tantalum-niobium ores refer to terrestrial minerals containing tantalum and niobium. There are more than one hundred species. Among them, tantalum, niobium and pyrochlore are the main minerals that can be mined. Tantalum (Ta) and niobium (Nb) are rare metals with high melting point (tantalum 2996℃, niobium 2468℃), high boiling point (tantalum 5427℃, niobium 5127℃). They have steel-like appearance, gray gloss and dark gray powder, and have the characteristics of gas absorption, corrosion resistance, superconductivity, unipolar conductivity and high strength at high temperature. It is used to prepare tantalum oxide and niobium oxide, and to extract tantalum and niobium. Grade analysis can be carried out quickly by a special wave-sonic ore analyzer for tantalum-niobium ores.
