Figure 5

EPMA back scattered electron image along with mineral phase identification and Rietveld analysis results. Elemental mapping results for the target elements: Al, Fe, Si, P, Dy, Y, La, Ce, and Nd in S1 ion-adsorption clay size fraction (< 0.25 mm) are also presented. For comparison, the compositional analysis obtained from ICP-OES and ICP-MS are presented in yellow boxes on each panel.
