Assessment of scandium deportment and recovery potential in Li-Sn-W greisen deposit Cinovec/Zinnwald using EPMA, LA-ICP-MS and TIMA automated mineralogy

Original language description

We investigated Sc content in minerals from Cinovec/Zinnwald greisen deposit. The highest content of Sc was found in ixiolite (avg. 2.09 wt.% Sc2O3), columbite (avg 1.34 wt% Sc2O3) and zircon (avg. 0.59 wt% Sc2O3). Three chemically distinct types of wolframite containing in avg. 0.06, 0.2 and 0.58 wt% Sc2O3, respectively were recognized. Cassiterite contains in average 0.068 wt% Sc. From the rock forming minerals, significant content of Sc was found only in zinnwaldite (avg. 63 ppm Sc) and muscovite (avg. 25 ppm Sc), whereas quartz, topaz, albite and K-feldspar contain very low Sc. TIMA was used to measure mineral mass proportions, grain size, deportment of elements and bulk composition of the samples. Because of low content of zircon and columbite in the studied rocks, they host significant fraction of whole rock Sc budget only in mica poor granites (similar to 6 ppm Sc bulk). Higher bulk Sc concentrations in greisens are controlled predominantly by amount of micas (especially zinnwaldite) and the most Sc-rich samples (up to similar to 290 ppm Sc) are the ones most rich in wolframite. Grain size measurements showed, that median grain size of zircon, columbite, xenotime and ixiolite (10-40 mu m) is several times lower compared to wolframite and cassiterite.
