tantalum ore columbium

  • TANTALUM, COLUMBIUM, AND FERROCOLUMBIUM

    Tantalum and columbium ores are processed by physically and chemically breaking down the ore to form columbium and tantalum salts or oxides, and separating the columbium and tantalum salts or oxides from each other. These salts or oxides may be sold, or further processed to reduce the salts to the respective metals.

  • Coltan Wikipedia

    Coltan (short for columbite–tantalites 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-dominant

  • Niobium (Columbium) and Tantalum Statistics and

    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.

  • 1 L.D. Cunningham, Columbium (Niobium) and Tantalum

    Columbium (the commonly used synonym for the element niobium) is used as an alloying element in steels and in superalloys. Tantalum and columbium are oft en found together in pyrochlore and baripyrochlore, the main columbium containing minerals, as well as in columbite.

  • Columbium and Tantalum Fabrication ASTM International

    However, since the known potential ore reserves of tantalum are estimated to be one tenth that of columbium it is expected that more columbium will be utilized than tantalum if only for economic reasons. Inasmuch as the fabrication procedures for columbium and tantalum are dependent to a large extent upon the raw material and method of consolidation, a review of these processes is in order
