Gold mining process produces wastes that contaminate the environment by As. • Bacterial strains of soils from mining region were resistant to 3000 mg L −1 of As.. Reduced 71.88% of arsenite and 85.72% of arsenate from the culture medium.
Rio Tinto: The Rio Tinto is an extremely acidic river in southern Spain.Enduring over 5000 years of mining activity, the river is full of heavy metals. Surprisingly, phylogenetic studies show the diversity of eukaryotes to be much greater than that of prokaryotes.
Bacteria - Bacteria - Bacteria in industry: Anaerobic sugar fermentation reactions by various bacteria produce different end products. The production of ethanol by yeasts has been exploited by the brewing industry for thousands of years and is used for fuel production. Specific bacteria carry out the oxidation of alcohol to acetic acid in the production of vinegar.

Since the identification and characterization of iron and sulfur oxidizing bacteria in the 1940s, a rapid progress is being made in minerals engineering based on biological activities. Microorganisms can play a beneficial role in all facets of minerals processing, from mining to waste disposal and management. Some of the applications, such as biologically assisted leaching of copper sulfide ...
Thus, the energy consumption at the mining site is less. Bioleaching currently accounts for an estimated 20 percent of the world's mined copper, and is in use at about 20 mines around the world. An acidic solution containing bacteria is applied and allowed to percolate through the .
That's why researchers have become increasingly keen to get these microbes on the mining payroll. They're looking for ways to use bacteria and archaea to extract metal from rock as well ...

The experimental mining kit will use bacteria to study how microorganisms can be used to extract minerals and metals from rocks on asteroids, moons, and planets. SUBSCRIBE. LOG IN.
Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of the earth's crust. Bacteria also live in symbiotic and parasitic relationships with plants and animals.
