  • Bioleaching (Biomining) Advantages, Process More

    The 3 most common commercial biomining processes are: 1. Slope Leaching. Fine ore is kept in a large, slope-shaped dump. During slope leaching, a water solution made of inoculum is continuously sprayed over the ore. After that, the leach liquor (or remaining liquid) is gathered at the bottom and processed for supplemental metal recovery. 2.
