The chemical formula of niobium-iron ore-tantalite is AB2O6, both of which are referred to as niobium-tantalum. Where A in the formula stands for iron and manganese, and B stands for niobium and tantalum. The magnetization rate of niobium-iron ore-tantalite is (22.1 to 37.2) × 10-6. The dielectric coefficient of niobium-iron ore is 10 to 12 ...

The procedure was repeated through a roll setting of 1.6 mm and a 1.67-mm screen. The combined coarse mica from the three screens comprised 41% of the feed weight and contained 4.9% of the tantalum and 7.9% of the niobium. This lost tantalum and niobium was considered part of the mica lattice rather than unliberated material.
