COLUMBITE-TANTALITE {COLTAN} MINING IN NIGERIA; THE OPPORTUNITIES
Columbite, also called niobite, niobite-tantalite and columbate, is a black mineral group that is an ore of niobium and tantalum. It has a submetallic luster and a high density and is a niobate of iron and manganese, containing tantalate of iron. Columbite and tantalite are collectively known as coltan in Africa.

Tantalite
The two are often grouped together as a semi-singular mineral called columbite-tantalite in many mineral guides. However, tantalite has a much greater specific gravity than columbite (8.0+ compared to columbite's 5.2).[1] Iron-rich tantalite is the mineral tantalite-(Fe) or ferrotantalite and manganese-rich is tantalite-(Mn) or manganotantalite.

Tantalite Gem Guide and Properties Chart
Manganotantalite. Manganotantalite is an intense red to reddish brown variety of tantalite with a high manganese and low iron composition. Prized for its exceptional dispersion, this mineral yields beautiful faceted gemstones, thanks in large part to its orthorhombic crystal structure. However, faceted gems are very limited in availability.
