Columbite: The mineral columbite-tantalite information and

Columbite forms a solid solution series with Tantalite known as the Columbite-Tantalite series. 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.

LA-ICP-MS dating of high‑uranium columbite from no. 1

Jun 01, 2020· 1. Introduction. Columbite-tantalite group minerals (CGMs) as an important source for strategic elements, Nb and Ta, frequently occur in highly evolved granites and granitic pegmatites (Linnen et al., 2012).These minerals share a common chemical formula AB 2 O 6 in which A represents divalent cations including Fe 2+, Mn 2+, and rarely Mg 2+ and B is occupied by Nb 5+ and Ta 5+ (Cěrný and

Coltan [Columbite-Tantalites] Ore

Mar 23, 2018· Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalumare are extracted. The niobium-dominant mineral in coltan is columbite (after niobium’s original American name, columbium), and the tantalum-dominant mineral is tantalite.. Columbite has the same composition and crystal symmetry
