or use of microorganisms in copper extraction from mineral ore

「Microbial Bioremediation Boundless Microbiology」

Microbial ore leaching (bioleaching) is the process of extracting metals from ores with the use of microorganisms. This method is used to recover many different precious metals like copper, lead, zinc, gold, silver, and nickel. Microorganisms are used because they can: lower the production costs.

「The Extraction of Metals from Ores Using Bacteria」

This chapter discusses the use of acidophilic, autotrophic bacteria in the extraction of metals. Microorganisms are responsible for the precipitation of a range of metal compounds out of solution, notably oxide, sulfide, and carbonate minerals. Two fundamentally different mechanisms may be envisaged for such mineral formation.

「Bacterial consortium for copper extraction from sulphide」

However, at the end of the test in Figure 2, the consortium achieved a good extraction of copper, being in second place. There is a difficulty in the extraction of copper from different bacterial consortium, due to the large amount of chalcopyrite present in the mineral studied (70% total Cu).

「Biomining Wikipedia」

Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes or fungi. These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons. It was discovered in the mid 1900s that microorganisms use metals in the cell.

「Zinc extraction from Iranian lowgrade complex zinclead」

This study was designed to investigate a biological extraction method to zinc recovery from lowgrade complex zinclead ore by two indigenous microorganisms: A. ferrooxidans and Sulfobacillus in shake flasks. 2. Material and methods 2.1. Ore characteristics. A complex zinclead sulfide ore supplied by Kooshk lead and zinc mine (Yazd, Iran

「The use of microorganisms and plants in metal extracting」

The kinetics of the bioleaching of a lowgrade copper ore was studied in a pilotscale leaching column over a period of 360 days using an opencircuit leaching regime with a fresh sulfuric acid

「Methods of Metal Recovery by Microorganisms (2 Methods)」

Methods of Metal Recovery by Microorganisms (2 Methods) In fact, microorganisms can be successfully used for the extraction of metals (e.g., copper, zinc, cobalt, lead, uranium) from low grade ores. Mining with microbes is both economical and environmental friendly. Bioleaching of copper ore (chalcopyrite) is widely used in many countries.
