This chapter explains the manifold geobiotechnological possibilities to separate industrial valuable metals from various industrial residues and stored waste products of the past. In addition to an overview of the different microbially catalyzed chemical reactions applicable for a separation of metals and details of published studies, results of many individual investigations from various research projects are described. These concern the separation of rare earth elements from phosphorous production slags, the attempts of tin leaching from mining flotation residues, the separation of metals from spent catalysts, or the treatment of ashes as valuable metal-containing material. The residues of environmental technologies are integrated into this overview as well. The description of the different known microbial processes offers starting points for suitable and new technologies. In addition to the application of chemolithoautotrophic microorganisms the use of heterotrophic microorganisms is explained.
本章阐述了从各种工业废渣和过去储存的废品中分离具有工业价值金属的多种地质生物技术可能性。除了概述适用于金属分离的不同微生物催化化学反应以及已发表研究的细节外，还描述了来自各种研究项目的许多单独调查结果。这些包括从磷生产矿渣中分离稀土元素、从采矿浮选残渣中浸出锡的尝试、从废催化剂中分离金属，或把灰烬作为含金属的有价值材料进行处理。环境技术的残渣也纳入了这一概述。对不同已知微生物过程的描述为适用的新技术提供了起点。除了化能自养微生物的应用外，还解释了异养微生物的使用。
