Bioleaching is a process that uses bacteria to extract metals from their ores. Here are some key points about bioleaching bacteria and their uses:
What they do: Bioleaching bacteria, mainly Thiobacillus ferrooxidans and T. thiooxidans, convert insoluble metal sulfides into soluble metal sulfates. This process is used to recover many different precious metals like copper, lead, zinc, gold, silver, and nickel.
How it works: In one proposed method of bacterial leaching known as Indirect Leaching, Fe 3+ ions are used to oxidize the ore. The role of the bacteria is further oxidation of the ore, but also the regeneration of the chemical oxidant Fe 3+ from Fe 2+1.
Applications: Bioleaching is used essentially for the recovery of copper, uranium, and gold, and the main techniques employed are heap, dump, and in situ leaching. It is also used for metal recovery and detoxification of industrial waste products, sewage sludge, and soil contaminated with heavy metals.
Environmental Impact: Bioleaching is an environmentally friendly method of extracting metals. As the bacteria feed, they expose rare-earth metals, which run off in the water fed through the rock. Because the valuable metals are in the run-off, the bioleaching system is contained, meaning less pollution than traditional methods.
Please note that the effectiveness of bioleaching can vary depending on the specific conditions and the types of ores present.
