Formula: (Fe,Mn)(Nb,Ta) 2 O 6 Orthorhombic Description: Columbite-tantalite refers to a group of minerals having varying amounts of iron, manganese, niobium, and tantalum. They are found as platey black grains in complex granitic pegmatites. DODGE COUNTY: Tiny prismatic crystals of manganocolumbite and manganotantalite were seen in pegmatites cutting quartzite in the Michels

Occupational Radiation Exposures of Artisans Mining

Artisans in Masisi and other parts of the North Kivu province in the eastern Democratic Republic of Congo (DRC) mine columbite-tantalite mineral ores (also called 'coltan') for the tantalum content. The potential occupational radiation exposures in the course of this operation, due to the presence of naturally occurring radioactive material (NORM), have been investigated in this screening survey

Columbite: The mineral columbite-tantalite information and

Columbite is the niobium-rich member, and Tantalite is the tantalum-rich member. Columbite is named after its niobium content, which was previous known as columbium prior to its renaming. Columbite is the most important mineral containing the rare element niobium and is its main ore. The name Columbite has been discredited by the IMA, with the

The African Tantalite Mining Industry

Chemically, tantalite is similar to columbite, and the two minerals are often grouped together in mineral guides. However, the specific gravity of tantalite is significantly higher than that of columbite. Tantalite is challenging to process and is therefore not extensively mined despite the rising demand for it as it
