| 内容記述 | Bacterial leaching was combined with thiourea method for the gold leaching from ores. For gold bearing pyrites, biological pre-oxidation has been generally perfomed. In the present study, we carried out the biological treatment to the high silicate bearing ores by using the iron oxidizing bacteria, Thiobacillus ferrooxidans. The recovery of gold and silver was enhanced by the biological pretreatment, while the effects of the treatment was influenced by the types of gold ores. Since the biological treatment was carried out in sulfuric acid solution, the results were compared with that of chemical treatment. The extraction of gold from the Hishikari ore with the bacteria was 10 to 20 % higher than that from the ore only chemically treated. On the other hand, the extraction of silver only slightly increased with the biological treatment. In addition, Thiobacillus ferrooxidans was directly inoculated in the thiourea leach solution for gold dissolution. About 20 % increase in the extraction of gold was observed for the Hishikari ore. | |||||||||||||||||
