Bioleaching - Wikipedia

Bioleaching can involve numerous ferrous iron and sulfur oxidizing bacteria, including Acidithiobacillus ferrooxidans (formerly known as Thiobacillus ferrooxidans) and Acidithiobacillus thiooxidans (formerly known as Thiobacillus thiooxidans).As a general principle, Fe 3+ ions are used to oxidize the ore. This step is entirely independent of microbes.
