2582 Figure 1 – Scanning electron micrographs of +850 µm size fraction with a) quartz (Si2O) with fluorite grains (CaF2) Figure 2 – Scanning electron micrographs of +850 µm size fraction with microcline (Mic), quartz (Si2O), and lithium mica (lepidolite) For the size fraction -850/+500 µm, liberated crystals of spodumene and lithium mica (Figure 3a and 3b), amphibole, and quartz were identified. Also, middling particles with Ti, Zr, Cr, and Fe intergrowth were identified (Figure 4). Figure 3 – a) Spodumene and b) lithium mica particles
