Bioleaching: metal solubilization by microorganisms

Abstract. Bioleaching is a simple and effective technology for metal extraction from low-grade ores and mineral concentrates. Metal recovery from sulfide minerals is based on the activity of chemolithotrophic bacteria, mainly Thiobacillus ferrooxidans and T. thiooxidans, which convert insoluble metal sulfides into soluble metal sulfates.Non-sulfide ores and minerals can be treated by ...

Phytomining & Bioleaching By Lucy Patterson (Sophie's Sibling)

The process is more environmentally friendly than traditional extraction methods. Less profit is made from bioleaching which means it is less appealing to buisness men and women. Bioleaching can extract metals from ores that are too poor for other technologies which means less waste. Toxic chemicals are also sometimes produced in this process.
