tantalite iron manganese tantalum niobium oxide

TANTALITE (Iron Manganese Tantalum Niobium Oxide)

Tantalite 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, 8.0+ compared
