    Bioleaching - an overview | ScienceDirect Topics

    Little difference in the bioleaching efficiency between one-step and two-step methods was observed in the case of the spent NiMo/Al 2 O 3 catalyst. Thus, for the spent catalyst as received, the extractions of Al, Ni, and Mo were similar, as it is shown in Fig. 11.11 [650].However, for smaller particles (e.g., 100–150 μm and <37 μm), the dissolution of Ni and Mo was higher than that of Al.
