· Tantalum (Ta) and niobium (Nb) are essential metals in modern society. Their use in corrosion prevention, micro-electronics, specialty alloys and high-strength low-alloy (HSLA) steel earns them a strategic designation in most industrialised countries. The Ta market is unstable due in part to historic influx of ‘conflict’ columbite-tantalite

Summary. Niobium and tantalum do not occur naturally as free metals. The charge to ionic ratio of tantalum and niobium results in strong bonds being formed with oxygen; in fact, most niobium–tantalum minerals are oxides, rather than silicates, sulfides or phosphates. Three types of niobium and tantalum deposits are: carbonatite-hosted
