FIGURE 7.7 SEM images of AS grains after abiotic (A1 and A2) and
biotic leaching (B1-C2) with A. thiooxidans.
Arrows indicate: A1: glass fracturing, A2: Cu-droplets removal, B1: glass fractionation,
B2: glass dissolution and Cu-droplets removal (GMB PD: 3%), C1 and C2: Amorphous slag
fractures (GMB PD: 1%).
