Columbite - an overview ScienceDirect Topics

Zaraisky et al. (2010) determined the solubility of Ta 2 O 5 and Ta-bearing columbite in F− -, Cl − -, HCO 3− -, and CO 32 − -bearing solutions at 300–550 °C. The presence of F − increased the solubility of both phases by several orders of magnitude, indicating formation of F- or OH–F-bearing aqueous complexes.

Occurrence and Composition of Columbite-(Fe) In the ...

Columbite-(Fe) is a post-magmatic accessory mineral occurring within syenogranites and greisens from the Desemborque Pluton. The petrographic (SEM) and geochemical (EPMA and LA-ICPMS) examination of this mineral shows two distinct textural types within both the rocks, named columbite-1 and columbite-2. The columbite-1 type is characterized by zoned crystals with two stages of
