Moreover, it permits extraction from low grade ores – an important consideration in the face of the depletion of high grade ores. The acidophilic archaea Sulfolobus metallicus and Metallosphaera sedula can tolerate up to 4% of copper and have been exploited for mineral biomining. Between 40 and 60% copper extraction was achieved in primary ...
