tantalum niobium ores

What is tantalum used for in everyday life? Explained by FAQ Blog Tantalum and Niobium are the most chemically linked pair of RMs. They are typically found together in the ore columbite-tantalite coltan . Why is coltan bad? Coltan mines operate under boom-bust economics and not only strip the mineral from the land, but also cause environmental degradation. Extract Tantalum Niobium from PegmatitesSpecific identified tantalum-niobium minerals found in the area are tantalite-columbite [ Fe, Mn Ta, Nb2 O6], tapiolite FeTa2O6 , and pyrochlore-microlite Ca2Ta2O7 .
