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 processing - Niobium processing - The metal and its alloys: Demands in the construction, transportation, and energy industries for stronger, tougher, more formable, and more weldable steel brought the development of the family of HSLA steels. As noted above, the addition of niobium to these steels gives rise to the improved properties while allowing a decreased use of carbon and manganese.Get Price

Apr 24, 2017 · Most tantalum mines are open pit; some are underground. The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum. The ore is then concentrated at or near the mine site, to increase the percentage (by weight) of tantalum oxide and niobium.Get Price
