Columbite mineral Britannica

Columbite, hard, black (often iridescent), heavy oxide mineral of iron, manganese, and niobium, (Fe, Mn)Nb 2 O 6. Tantalum atoms replace niobium atoms in the crystal structure to form the mineral tantalite, which is similar but much more dense.These minerals are the most abundant and widespread of the naturally occurring niobates and tantalates and are important ores, their

niobium processing History, Ores, Mining, & Extraction

Ores. Niobium occurs mostly as an oxide and has a strong geochemical coherence with tantalum. Major minerals of niobium are pyrochlore [(Na, Ca) 2 Nb 2 O 6 F] and columbite [(Fe, Mn)(Nb, Ta) 2 O 6], consisting of niobate, tantalate, iron, and manganese.Pyrochlore occurs usually in carbonatites and in pegmatite derived from alkalic rocks, commonly in association
