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 ions are used to oxidize the ore. This step is … See more Bioleaching is the extraction of metals from their ores through the use of living organisms. This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within See more The dissolved copper (Cu ) ions are removed from the solution by ligand exchange solvent extraction, which leaves other ions in the solution. The copper is removed by … See more Economic feasibility Bioleaching is in general simpler and, therefore, cheaper to operate and maintain than traditional processes, since fewer specialists are … See more • Biology portal • Technology portal • Phytomining See more Several species of fungi can be used for bioleaching.
