The Future of Tantalum and Niobium - Mining Technology

Tantalite contains some niobium, with the mineral being referred to as niobite or columbite when the niobium content is greater than that of tantalum. Indeed, until the discovery of the world's pyrochlore deposits in the 1950s, niobium was a by-product of tantalum mining, with increasing demand ensuring that it was highly valued and highly ...

Coltan - Wikipedia

Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is the tantalite.. Tantalum from coltan is used to manufacture …

Separation Of Niobium And Tantalum Through Solvent

Tantulum and Niobium. Tantalum usually occurs with the chemically-similar niobium, often in tantalite and columbite, coltan (columbite + tanatalite), or polychlore (niobium). Tantalum ores, often derived from pegmatites, comprise a wide variety of more than a hundred minerals, some of which contain uranium and/or thorium.

Tantalum is also highly resistant to heat and generally non-reactive. Tantalum is a strong and conductive metal that is almost always found together with the element Niobium (Nb). Tantalum does not occur naturally as a pure metal, but is rather bound with oxygen and other elements in minerals such as tantalite (Table 1).
