Beschreibung
Zusammenfassung:	The invention discloses a bio-leaching process of low-grade copper ores, copper ore concentrates are doped into the copper ores according to a certain ratio, and are mixed uniformly and dumped, and then the bio-leaching is carried out, the bio-leaching and the acid producing are carried out at the same time, so the external sulfuric acid is not required during the biological dump leaching process of the copper ores, the acid balance in the dump leaching system is realized, and furthermore, the higher activity of the bacteria is guaranteed, the leaching speed and efficiency are improved, the medicament cost is low, the copper leaching effect is favorable, the method is simple, the industrialization is facilitated, and so the process is a novel, effective and high-controllability copper ores biological copper extracting process.
