Columbite has the same composition and crystal symmetry (orthorhombic) as tantalite. In fact, the two are often grouped together as a semi-singular mineral series called columbite-tantalite or coltan in many mineral guides. However, tantalite has a much greater specific gravity than columbite, more than 8.0 compared to columbite's 5.2.
Devil's Hole Quarry, Texas Creek Area, Fremont Co., Colorado, USA Ex. Kay Robertson. Columbite-Tantalite is a combination term that is used generically for the specimens in the Columbite/Tantalite families. Under normal circumstances, they are very difficult to tell apart.
