Biomining is a process that uses microorganisms to extract metals and other materials from ores and solid materials.

Here are some details about biomining

Microorganisms used

The most commonly used bacteria in biomining is Thiobacillus ferrooxidans, which can produce energy from oxidizing inorganic compounds like sulfur and iron. Other bacteria used in biomining include Thermothrix thiopara, which can survive high temperatures

Processes involved

Biomining involves two main processes: bioleaching and biooxidation. Bioleaching involves dumping low-grade ore into a heap and soaking it with acid and bacteria. Limitations

Limitations

Biomining can be slower than traditional mining processes and can only work in specific environments. Microbes will only target certain minerals, limiting the choice of minerals that can be mined.
