In the sixteenth century, heap leaching became commonly used to extract copper and saltpeter from organic matter. [4] Primarily used in Germany and Spain, pyrite would be brought to the surface and left out in the open. [4] [3] The pyrite would be set outside for months at a time, where rain and air exposure would lead to chemical weathering. [4]

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials.
The possibility of using microorganisms in biomining applications was realized after the 1951 paper by Kenneth Temple and Arthur Colmer. [9] In the paper the authors presented evidence that the bacteria Acidithiobacillus ferrooxidans (basonym Thiobacillus ferrooxidans) is an iron oxidizer that thrive in iron, copper and magnesium-rich environments.
