In situ U–Pb isotopic dating of columbite–tantalite by …
Abstract. Columbite–tantalite (Coltan) is the most important niobium (Nb)- and tantalum (Ta)-bearing economic mineral, commonly occurring in rare metal granite and pegmatite, alkaline granite, syenite and carbonatite. Its high U but low common Pb contents make it an ideal mineral for U–Pb isotopic dating of Nb–Ta mineralization.

Technical Summary – MANONO LITHIUM TAILINGS PEA
The Manono Lithium tailings are technogenic deposits, created from the processing of material from the Manono‑Kitolo deposit, which was mined from 1919 to the mid-1980's for tin and columbite-tantalite (coltan). Nine out of the eleven tailings were drilled, of which five form this Mineral Resource Estimate.

COLUMBITE-TANTALITE {COLTAN} MINING IN NIGERIA; THE OPPORTUNITIES
Columbite, also called niobite, niobite-tantalite and columbate, is a black mineral group that is an ore of niobium and tantalum. It has a submetallic luster and a high density and is a niobate of iron and manganese, containing tantalate of iron. Columbite and tantalite are collectively known as coltan in Africa.

Dissolution textures resulting from the corrosion of columbite and tantalite rims, in particular, are common. The Mn/(Mn + Fe) ratio varies between 0.33 and 0.97 and the Ta/(Ta + Nb) ratio between 0.07 and 0.93. Wodginite and microlite formed as late replacements of CGM and occur associated with tantalite and cassiterite.

Episodic Nb–Ta mineralisation in South China
From core to rim, CGM crystals vary from columbite-(Mn) to tantalite-(Fe), recording magmatic fractionation. The Gaoling quartz vein contains homogenous CGM crystals that yield low Ta concentrations ( Figs. 2 and 3 c), likely reflecting the action of a hydrothermal fluid, as Nb has a low solubility and is fluid-mobile ( Linnen et al., 2014 ).
