Figure 4
500 × 500 µm SPEM images from fractured air-oxidized chalcopyrite with bornite. (a) Background channel indicating topography and topography-corrected images from (b) Cu 3p and (c) Fe 3p. Topography-corrected images (d), (e) and (f) are from the S 2p signal from an energy channel on the multi-element detector of approximately 164 eV (d), 162 eV (e) and 161 eV (f). |
