Bacterial consortium for copper extraction from sulphide ore consisting mainly of chalcopyrite

Bioleaching of copper. · Recently, consortia of acidophilic bacteria such as At. ferrooxidans, At. thiooxidans, and Leptospirillum ferrooxidans have shown auspicious results for copper extraction from low-grade ores and a favored consortium for large-scale heap bioleaching process (Panda et al. 2012, 2015).

 · The bacterial consortium was isolated from activated sludge in an industrial wastewater treatment plant in Rungkut-Surabaya, Indonesia. The growth of bacterial consortium was monitored by measuring optical density at 600 nm. The ability of bacterial consortium to accumulate and biosorp copper were determined by atomic absorption …

In conclusion, it was found that the consortium integrated by At. ferrooxidans and At. thiooxidans removed 70% of copper in 35 days from the selected ore, showing significant …
