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 was identified by English chemist Charles Hatchett in 1801. He found a new element in a mineral sample that had been sent to England from Connecticut, United States in 1734 by John Winthrop F.R.S. (grandson of John Winthrop the Younger) and named the mineral columbite and the new element columbium after Columbia, the poetical name for the United States. The columbium discovered by Hatchett was probably a mixture of the new element with tantalum.

Coltan - Wikipedia

Coltan (short for columbitetantalites and known industrially as tantalite) is a dull black metallic ore from which are extracted the elements niobium and tantalum. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum

In 1809, William Hyde Wollaston made the wrong conclusion that columbium and tantalum were identical. In 1846, Heinrich Rose, a German chemist, discovered that ores of tantalum contained another element, niobium. By 1865, scientists discovered that columbium and niobium were one and the same, as well as distinct from tantalum.

Other, less common oxides of niobium and tantalum include tapiolite, ixiolite, and minerals of the perovskite group. Niobium and tantalum also substitute for major ions in some common oxide groups such as cassiterite, rutile, and ilmenite. Contents of niobium and tantalum in these minerals are rarely high enough to make them of economic interest.

Independently, Heinrich Rose discovered in 1846 that tantalum ore included a second element, which he named niobium. Nearly twenty years later, a series of experiments concluded that columbium and niobium were actually the same element.
