Columbite, also called niobite, niobite-tantalite and columbate [(Fe,Mn)Nb 2O 6], is a black mineral group that is an ore of niobium. It has a submetallic luster and a high density and is a niobate of iron and manganese. This mineral group was first found in Haddam, Connecticut, in the United States. It forms a series with the tantalum-dominant analogue ferrotantaliteand one with the manganese-dominant analogue manganocolumbite. The iron-rich member of the columbite group is ferrocolumbite.
