Tantalite and columbite are not uncommon as constituents of cassiterite bearing pegmatite veins, but in most cases the amounts found are small. Tantalite is found at many of the localities for columbite and also at several other places.
Tantalite is the form of this mineral which is principally a mixture of tantalates with a minimum of niobium. When the tantalite is composed almost exclusively of the manganese molecule (with little iron), it is known as manganotantalite. Tantalite occurs in granite rocks and in pegmatite veins, associated with quartz, feldspar, mica, tourmaline, beryl, spodumene, casseterite, samarskite, wolframite, microlite, monazite, etc. Tantalite has been found in Egypt, Brazil Namibia, Nigeria, Madagascar, Canada and Europe.
