The bioleachings of chalcopyrite ore were compared after inoculating different cultures enriched from the original acid mine drainage sample. The results showed that the higher bioleaching performance was achieved for inoculation with the enrichment D (0.5 % S, 2 % iron and 1 % chalcopyrite) compared to other enrichment systems. The generated ferric precipitation during bioleaching had a key influence on the final copper extraction. After enrichment, a higher ratio of iron-oxidizer and a higher ratio of sulfur-oxidizer existed in enrichments B and C, respectively. These created the different bioleaching behaviours from other systems. Maintaining a suitable equilibrium between iron- and sulfur-oxidizers is significant to decrease ferric precipitation or postpone its formation, and ultimately prolong efficient bioleaching period and improve copper extraction.
