However, the number of Ta Nb deposits including those of the granite type and the pegmatite type, are relatively less. On the basis of geology, petrology, geochemistry and mineralization data from 8 ore deposits and related granites, we suggest that the Ta Nb mineralized granites are the special products of well evolved granite magmas.

Dressing processes are carried out on ores containing up to hundredths of a percent of (Ta, Nb) 2 O 5 and on slags from the reduction smelting of tin concentrates. The main starting materials in the preparation of tantalum and tantalum alloys and compounds are tantalite and loparite concentrates, which contain approximately 8 percent Ta 2 O 5 and 60 percent or more Nb 2 O 5 .

Niobium

Niobium

Niobium, formerly known as columbium, is a chemical element with the symbol Nb (formerly Cb) and atomic number 41. Niobium is a light grey, crystalline, and ductile transition metal.Pure Niobium has a hardness similar to that of pure titanium [contradictory], and it has similar ductility to iron.Niobium oxidizes in the earth's atmosphere very slowly, hence its application in jewelry as a

Niobium (Columbium) and Tantalum Statistics and Information

Niobium (Columbium) and Tantalum Statistics and Information

Niobium and columbium are synonymous names for the chemical element with atomic number 41; columbium was the name given in 1801, and niobium (Nb) was the name officially designated by the International Union of Pure and Applied Chemistry in 1950. Niobium in the form of ferroniobium is used worldwide, mostly as an alloying element in steels and in superalloys.

Tantalum

Tantalum

Tantalite has the same mineral structure as columbite (Fe, Mn) (Ta, Nb) 2 O 6; when there is more tantalum than niobium it is called tantalite and when there is more niobium than tantalum is it called columbite (or niobite). The high density of tantalite and other tantalum containing minerals makes the use of gravitational separation the best method.
