a mineral consisting of tantalum oxide of iron and manganese that occurs with niobite or in coarse granite; an ore of tantalum
A dark-brown mineral that is an ore of tantalum and niobium, of the chemical formula (Fe, Mn) TaO.
a heavy mineral of an iron-black color and submetallic luster. It is essentially a tantalate of iron
The mineral group tantalite [Ta2O6] is the primary source of the chemical element tantalum. It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides. However, tantalite has a much greater specific gravity than columbite. Iron-rich tantalite is the mineral tantalite- or ferrotantalite and manganese-rich is tantalite- or manganotantalite. Tantalite is also very close to tapiolite. Those minerals have same chemical composition, but different crystal symmetry orthorhombic for tantalite and tetragonal for tapiolite. Tantalite is black to brown in both color and streak. Manganese rich tantalites can be brown and translucent.
