    Columbite-Fe, named for its iron (Fe) and niobium content, was formerly referred to as columbium or ferrocolumbite. This name derived from “Columbia,” a poetic reference to the United States, where the element was first discovered. It occurs primarily in granite pegmatites but is also found in carbonatites and placer deposits. Columbite-Fe is paramagnetic and found in various locations worldwide, including the United States (such as the Black Hills of South Dakota), Norway, Russia, Italy, Madagascar, Australia, and Japan.
