Copper, zinc, and iron bioleaching from polymetallic sulphide concentrate
Bioleaching of low-grade complex Cu–Zn–Pb–Fe–Ag–Au sulphide concentrate (of Majdanpek ore body, RTB Bor, Serbia) was carried out in an aerated bioleach reactor in the presence of mesophilic mixed bacterial culture of Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans, and Leptospirillum f...
