Cross‐Comparison of Leaching Strains Isolated from Two Different Regions: Chambishi and Dexing Copper Mines

BioMed Research International, Volume 2014, Issue 1, 2014., 2014
A cross‐comparison of six strains isolated from two different regions, Chambishi copper mine (Zambia, Africa) and Dexing copper mine (China, Asia), was conducted to study the leaching efficiency of low grade copper ores. The strains belong to the three major species often encountered in bioleaching of copper sulfide ores under mesophilic conditions ...
