1 11 th Rare Earth Conference Singapore RWTH Aachen workshop on green resources & processing concepts for rare earth metals Eudialyte, an unexploited resource for valuable heavy rare earth elements How to prevent the silica gel formation? Daniel Voßenkaul, B. Friedrich 1 Daniel Voßenkaul I Institute of Process Metallurgy and Metal Recycling I RWTH Aachen University
2 Eudialyte Empirical chemical fomula (Eudialyte): N 15 [M 1 ] 6 [M 2 ] 3 [M 3 ] M 4 Z 3 [Si 24 O 72 ]O 4 X 2 N = Na, Ca, K, Sr, SEE, Ba, Mn, H 3 O M 1 = Ca, Mn, SEE, Na, Sr, Fe M 2 = Fe, Mn, Na, Zr, Ta, Ti, K, Ba, H 3 O + M 3,4 = Si, Nb, Ti, W, Na Z = Zr, Ti, Nb O = O, OH, H 2 O X = H 2 O, Cl, F, OH, CO 3 2, SO 4 2, SiO 4 4 Johnson, O (2003): The nomenclature of eudialyte groupe minerals 2 Daniel Voßenkaul I Institute of Process Metallurgy and Metal Recycling I RWTH Aachen University
3 Advantages and Challenges Advantages of Eudialyte: High contents of heavy rare earth elements (HRE) (up to 50%) Easy to digest with mineral acids Contains other valuable metals like Zr, Mn, Nb & Ta Low contents of radioactive elements (Th & U) Available in Europe (Sweden, Greenland, Russia) Challenges for REE processing: Variable and low contents of total rare earth elements (treo) (< 10%) Tendency of gel formation High consumption of acids Difficult digestion of Zr (> 60%), Nb & Ta 3 Daniel Voßenkaul I Institute of Process Metallurgy and Metal Recycling I RWTH Aachen University
4 Direct Acid Leach of Eudialyte Critical silicon concentration in solution of about 500 mg/l Gelatinous Mass Finely Ground Ore Eudialyte Ore 4 Daniel Voßenkaul I Institute of Process Metallurgy and Metal Recycling I RWTH Aachen University
5 Mechanism of Silica Gel Formation Monosilicic acid Disilicic acid Polysilicic acid Boundary layer of colloids Fresh silica gel Colloid Enclosed liquid volume 5 Daniel Voßenkaul I Institute of Process Metallurgy and Metal Recycling I RWTH Aachen University
6 Theo. approach of silica gel prevention Prevention of enclosing water Minimisation of polymerisation Idea: Dry digestion of the Eudialyte concentrate for an immobilization of silica colloids Grinded Eudialyte concentrate Dry digestion with HCl Washing out with H 2 O Theoretical concept of dry digestion process: Similar chemical reaction (formation of an amorphous silica phase) Differences in structure less mobility of colloids individual fragments (less polymerization) Washing out of valuable metal chlorides (no solution of once stabilized silica) 6 Daniel Voßenkaul I Institute of Process Metallurgy and Metal Recycling I RWTH Aachen University
7 Process Parameter Study (25 g scale) t(dry digest) m(hcl) t(leaching) reproducibility Reproducible results (ore decomposing): No gelation by dry digest (correlation with silicon recovery) REE recovery > 90% Transferable to different Eudialyte occurrences: Khibina Complex Norra Kärr Ilimaussaq Complex (TANBREEZ) 7 Daniel Voßenkaul I Institute of Process Metallurgy and Metal Recycling I RWTH Aachen University
