A part of the tantalum in tantalite is almost invariably replaced by the closely allied metal niobium and when the amount of the latter exceeds the former the mineral is known under the name of columbite Tantalite is the form of this mineral which is principally a mixture of tantalates with a minimum of niobiumTantalite is the more tantalum rich end member and columbite is the more niobium rich end member Niobium had been called columbium hence the name columbite Tantalite s greatest difference from columbite is its much greater specific gravity 80 compared to columbite s 52 Other properties that vary slightly are color transparency and streak
