Mineralogical Characteristics of Pegmatite Tailings and Beneficiation Assessment of Pollucite in Recovering Cesium

The technological mineralogical characteristics of cesium-containing minerals in tailings were examined by means chemical analysis, the energy spectrum analysis method, and MLA (mineral liberation analyzer) to determine element content, phase associated mineral components, degree liberation, particle size, etc. results showed that samples mainly contained spodumene, quartz, feldspar, mica, other minerals. Pollucite was main sample, which had a cesium oxide content as high 34.58%. pollucite sample relatively low—only 1.23%. monomer amount rich intergrowth 85.25%, metal distribution +0.074 mm 87.06%. Spodumene with pollucite. beneficiation evaluation this tailing conducted using combined process integrated desliming, magnetic separation, froth flotation, concentrate containing 4.45% Cs2O obtained 63.71 recovery rate. This indicates little removed desliming separation before flotation recovery, but during stage spodumene large loss observed. Therefore, improve pollucite-specific adsorption reagent should be synthesized.
