these are the microbes used in copper extraction

Biomining is mineral processing with microbes. Biomining is the process of using microorganisms (microbes) to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals.

Bioleaching

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 . [1] Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper , zinc , lead , arsenic , antimony , nickel , molybdenum , gold , silver , and cobalt .

Copper Mining and Extraction Sulfide Ores

An ore is a rock or mineral that has enough metal in it to make it worth extracting. Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.

Innovations Introduction to Copper Mining & Extraction

Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores.

Bioleaching metal solubilization by microorganisms

Bioleaching is a simple and effective technology for metal extraction from low grade ores and mineral concentrates. Metal recovery from sulfide minerals is based on the activity of chemolithotrophic bacteria, mainly Thiobacillus ferrooxidans and T. thiooxidans, which convert insoluble metal sulfides into soluble metal sulfates. Non sulfide ores and minerals can be treated by heterotrophic bacteria and by fungi.
