SEM analysis of arsenopyrite particles. (A) Secondary electron image of clean size segregated arsenopyrite particles (B) Sample surface composition measurements of arsenopyrite using SEM-EDS. Comparison of SEM images between (C) arsenopyrite surface prior to acid treatment and (D) arsenopyrite surface after cleaning with 12N HCl reveals no significant morphological changes to the surface of the mineral.
