The Bioshale project, involving 13 partners throughout Europe, is co-funded by theEuropean Commission under the FP6 program. The main objective of this project (which started inOctober 2004) is to identify and develop innovative biotechnological processes for ‘’eco-efficient’’exploitation of metal-rich, black shale ores. Three extensive deposits have been selected for R&Dactions. These are: (i) a site (in Talvivaara, Finland) that, at the outset of the project, had not beenexploited; (ii) a deposit (in Lubin, Poland) that is currently being actively mined, and (iii) a thirdsite (in Mansfeld, Germany) where the ore had been actively mined in the past, but which is nolonger exploited. The black shale ores contain base (e.g. copper and nickel), precious (principallysilver) and PGM metals, but also high contents of organic matter that potentially handicap metalrecovery by conventional techniques.The main technical aspects of the work plan can be summarized as: (i) evaluation of the geologicalresources and selection of metal-bearing components; (ii) selection of biological consortia to betested; (iii) assessment of bioprocessing routes, including hydrometallurgical processing; (iv)techno-economic evaluation of new processes from mining to metal recovery including social, and(v) assessing the environmental impacts of biotechnological compared to conventional processingof the ores. An overview of the main results obtained to date are presented, with special emphasison the development of bioleaching technologies for metal recovery that can be applied to multielementconcentrates and black shale ores
