Pretreatment of copper-bearing refractory gold ores by bio-heap leachingYanling Sheng,Qiang Zhang, Huajun Wang, and Yanru Sheng Civil and Environmental Engineering School, University of Science... gold ores associated with rich copper and trapped in pyrite and quartz were studied. With conventional technique (all-sliming cyanidation), the gold recovery rate is only 51.78%. To eliminate......
Bioleaching of zinc from gold ores using Acidithiobacillus ferrooxidansPakawadee Kaewkannetra1,Francisco Jose Garcia-Garcia2,Tze Yen Chiu31. Department of Biotechnology,Faculty of Technology,Khon...">The present work investigated microbial leaching of zinc from ore using Acidithiobacillus ferrooxidans (ATCC 14859). The ore samples, consisted of 13wt% zinc, were obtained from a gold mine in north-eastern......

, the methods for treating gold ores are mainly cyanogens, thiourea, thiosulfate, and halogen approach, among which, the cyanogens approach has the advantages of low cost, high efficiency, and now is the main method for producing gold. However, the effect of leaching complicated ores with this method is very poor, due to its low leaching speed and easy effect by elements such as Cu, Fe, Pb, Zn, S......
