Microbiological Mining - Spaceship Earth

MICROBIAL MINING. The recovery of copper from the drainage water of mines was probably a widespread practice in the Mediterranean basin as early as 1000 B.C. Although such mining operations are difficult to document, it is known that the leaching of copper on a large scale was well established at the Rio Tinto mines in Spain by the 18th century.
