Biomining | PPT
Bio mining uses microorganisms like bacteria and fungi to extract metals from ores. It involves two main processes: bioleaching and biooxidation. Bioleaching involves dumping low-grade ore into a heap and soaking it with acid and bacteria, which degrade the ore and release minerals into fluid. This technique is commonly used to extract gold ...
