Scientists first recognised importance of certain bacteria for the extraction of metals from ore in the 1950s. Nowadays the microbial ore leaching with so-called 'lean ores' represents more than 10% of the total production of copper in the USA alone. The bioreactor shown here can be used to clearly demonstrate to the students this method of extraction (e.g. copper from copper ore) using such bacteria (Thiobacillus ferrooxidans).
