International audience; We describe the geological context of rare metal-bearing pegmatites from the Mangodara district (South-West Burkina Faso, Paleoproterozoic West African Craton) and discuss their petrogenesis and links with the host rocks. The

Mineralogical Characterization of Heavy Mineral Concentrates from Senegalese Great Cost by Using Qemscan and SEM

Autor: Simon B. Blancher, Abdoul Aziz Ndiaye, Moumar Dieye, Marieke Van Lichtervelde, Mamadou Gueye

Publikováno v: International Journal of Geosciences. 11:800-817

The heavy mineral sands of Senegal are exploited to extract titanium oxides and zircon. Mining is carried out first by means of a floating dredge and concentration plant which produces a heavy mineral concentrate (HMC) containing on average 78% titan

Solubility of Monazite–Cheralite and Xenotime in Granitic Melts, and Experimental Evidence of Liquid–Liquid Immiscibility in Concentrating REE

Autor: Philippe Goncalves, Aurélien Eglinger, Marieke Van Lichtervelde, Nicolas Dacheux, Aurélia Colin, Jean-Marc Montel

Publikováno v: Journal of Petrology. 62

We provide new experimental data on monazite, xenotime and U–Th-bearing cheralite solubility in slightly peralkaline to peraluminous granitic melts using dissolution and reverse (i.e. recrystallization after dissolution) experiments in water-satura

International audience; Columbite-tantalite group minerals are the most common Nb-Ta minerals. Columbite-tantalite is particularly suitable for U-Pb dating due to its high U and low common Pb contents. In situ isotopic dating of columbite-tantalite b
