in nature. It has been well documented that these metals are constantly solubilized by microbiological action in nature [2]. Consequently, Acidithiobacillus ferrooxidans, an acidophilic... of the environment. Acidithiobacillus ferrooxidans is known to develop extraordinary tolerance to metals which are often toxic to other micro-organisms. Numerous researchers [3-7] have documented......

悬臂式掘进机的有效使用范围及其发展前景A.A.库济明,姜荣超摘 要:<正> 目前国内机械制造厂批量生产四种型号的悬臂式掘进机,即4-3P 和轻型掘进机,4-2M 中型掘进机和4-5重型掘进机.根据 A.A.斯阔琴斯基矿山研究所的资料,为保证矿井正常的工作条件和减少巷道的维护费用,在煤层和软岩中,开拓与采准巷道的净断面不应小于12米2.目前基洛夫机械厂批量生产的掘进机可掘进断面不超过15米2的巷道,不能满足增大掘进断面的要求.此外,该机在技术和结构参数方关键词:......
pH 3.5 within a month, which is even higher than that of A. ferrooxidans or the mixed culture with A. ferrooxidans at even lower pH. Key words: Acidiphilium sp.; bioleaching; marmatite; chalcopyrite... for bioleaching are mainly chemoautotrophs, such as Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans and Leptospirillum spp., that gain energy by oxidization of ferrous iron (Fe2+), sulfur (S0......
