In the past few years, the mining industry has been turning to more efficient and environmentally salubrious method for extracting minerals from ores. The use of bacterium thiobacillus ferooxidans to leach copper from mine tailings has improved recovery rates and reduced operating costs to a large extent.
Thiobaccillus ferooxidans, is naturally present in certain sulfur containing materials .The bacterium thiobaccillus ferooxidans obtains energy by oxidizing inorganic materials, such as copper sulfide minerals. This process releases sulfuric acid and an oxidizing solution of ferric irons, which can wash out metals from crude ore. Poor quality copper ore is treated with sulfuric acid to facilitate the growth of the bacterium.
Bioming is the most important of application of biotechnology today.Bioming is alsoused to extract gold from very low grade sulfide gold ores.
The National Institute of Science and Media along with distinguished writer Joel Ball publish various study resources on biotechnology and the other branches of biology.
