简介:在过去的十年,biohydrometallurgy的领域里的进步是重要的。17新奇biomining微生物的一个总数被发现,并且八铜堆bioleaching种并且11黄金biooxidation植物被建立或膨胀。在这评论,它被总结为学习微生物引起的社区动力学和结构的最新孤立的biomining微生物和三个新奇微生物引起的生态的方法的生理的性质。另外,关于象铀,铝,碲,金者,铟,和第二等的稀罕金属资源那样的稀罕金属的biohydrometallurgy研究,以及象铜,镍,钴,和黄金那样的重非铁的金属被考察了,与在中国的一个重音。在未来,黄铜矿,稀罕金属,从废物的第二等的资源,和资源利用引起的环境污染的bioleaching上的进一步的研究是必要的。图形的AbstractZijinshan堆bioleaching植物与30,000的能力在2012重启操作?tonent蠨?蠨吗??

简介:稀土元素金属(雷姆)是在高技术,发电,通讯,和防卫工业有普遍、唯一的应用的一系列17个元素。这些资源对突现的持续精力和碳选择技术也枢轴。雷姆的恢复由于它与各种各样的工业应用一起的高市场价格有趣。常规技术,viz。降水,过滤,液体液体抽取,稳固液体的抽取,离子交换,超级批评抽取,电迷,电精制,精制的electroslag,等等,为雷姆的恢复被开发了,不是经济地吸引人的。Biosorption从水的答案为稀土元素金属的恢复代表biotechnological革新以及一个合算的优秀工具。许多biomaterials象水藻那样,真菌,细菌,树脂,激活的碳,等等,被报导了为雷姆的恢复用作潜在的吸附物。影响稀土元素金属并且等温线建模的举起的金属绑定机制,以及参数这里被介绍。这篇文章提供过去的成就和用答应biosorbents能为恢复雷姆用作一个节俭的工具的一些执行的biosorption研究的当前的情形的概述。不同工人报导的试验性的调查结果将提供卓见进这研究边疆。
