“…One of the research streams in the Bioshale FP6 project [228] was directed towards process developments for the copper-and silver-enriched black shale ore and concentrate from Lubin mine and concentrator, Poland. The copper concentrator also produced a middling shale fraction that had similar properties to the shale ore but caused problems in the flotation plant.…”

“…Jowitt and Keays [276] reported that there had been significant research in three of the shale-hosted nickel regions, either because of their size or because of the high metal grades; they are the Talvivaara deposit in Finland, a number of nickel-molybdenum deposits in southern China (e.g., Zunyi and Zhijin, Guizhou province; Dayong and Cili, Hunan, Dexhe, Yunnan, Duchang, Jiangxi and Lizhe, Zhejiang [291]), and deposits in the Selwyn Basin, Yukon, Canada. Copper-enriched polymetallic black-shale ores and their concentrates have been a focus of two large, international projects supported by the European Union, the BioMinE project [292] and the BioShale FP6 project [228]. It should be noted that, while grades or deposit size might preclude the development of economic processes for today's industry, smaller, lower-grade deposits might become economic in the future [276], particularly in view of the success of the Talvivaara heap bioleaching process [238] and the pilot-scale studies on Kupferschiefer concentrates and ores [228].…”

“…Complementary laboratory-scale experimental and theoretical studies included the application of bioflotation to increase the amount of concentrate obtainable and/or its grade, and modelling-simulation of heat transfer in heap bioleaching using data from both the pilot crib operated by the Geological Survey of Finland and the pilot heap conducted at Talvivaara mine [228].…”

“…The body of research within the BioShale FP6 European project on processing of the "Kupferschiefer" black shale follows the historical trend of focusing on copper and silver extraction [153,[307][308][309] but with broad research objectives [228]: to assess bioprocessing methods and complementary processing routes for hydrometallurgical recovery of metals, undertake a risk assessment regarding waste management and a techno-economic evaluation of new processes, and to characterise microbial communities engaged in leaching.…”

This review has as its underlying premise the need to become proficient in delivering a suite of element or metal products from polymetallic ores to avoid the predicted exhaustion of key metals in demand in technological societies. Many technologies, proven or still to be developed, will assist in meeting the demands of the next generation for trace and rare metals, potentially including the broader application of biohydrometallurgy for the extraction of multiple metals from low-grade and complex ores. Developed biotechnologies that could be applied are briefly reviewed and some of the difficulties to be overcome highlighted. Examples of the bioleaching of polymetallic mineral resources using different combinations of those technologies are described for polymetallic sulfide concentrates, low-grade sulfide and oxidised ores. Three areas for further research are: (i) the development of sophisticated continuous vat bioreactors with additional controls; (ii) in situ and in stope bioleaching and the need to solve problems associated with microbial activity in that scenario; and (iii) the exploitation of sulfur-oxidising microorganisms that, under specific anaerobic leaching conditions, reduce and solubilise refractory iron(III) or manganese(IV) compounds containing multiple elements. Finally, with the successful applications of stirred tank bioleaching to a polymetallic tailings dump and heap bioleaching to a polymetallic black schist ore, there is no reason why those proven technologies should not be more widely applied.

Hugues. Relationship between bioleaching performance, bacterial community structure and mineralogy in the bioleaching of a copper concentrate in stirred-tank reactors. Applied Microbiology and Biotechnology, Springer Verlag, 2011, 89 (2) The experiments undertaken to produce the techno-economic data were also an opportunity to carry out more fundamental research. The objective of this work was to combine the results of the bioleaching experiments, in terms of copper recovery, with the results of bacterial community monitoring and mineralogy residue analysis.Batch and continuous bioleaching tests were carried out with 10% solids, at 42 °C and with a pH between 1.2 and 1.6. Final copper recovery was higher in batch cultures than in continuous mode (>95% vs. 91%). Mineralogical analysis showed that the limiting factor for copper recovery was incomplete chalcopyrite dissolution in both cases. However, chalcopyrite was even less dissolved in continuous conditions. This was also related to a variation in bacterial community structure. The population in all tests was composed of Acidithiobacillus caldus, Leptospirillum ferriphilum and one or two species of Sulfobacillus (thermosulfidooxidans and sometimes benefaciens) but Sulfobacillus and more generally sulphur oxidizers were more represented in batch mode.It was proposed that, due to their capacity to reduce inorganic compounds, sulphur oxidizers may be efficient in limiting chalcopyrite surface hindering. It may help to better dissolve this mineral and reach a better copper recovery.

Alkaliphiles are interesting groups of extremophilic organisms that thrive at pH of 9.0 and above. Many of their products, in particular enzymes, have found widespread applications in industry, primarily in the detergent and laundry industries. While the enzymes have been a runaway success from the industrial point of view, many more products have been reported from alkaliphiles such as antibiotics and carotenoids. Less known are their potential for degradation of xenobiotics. They also play a key role in biogeocycling of important inorganic compounds. This review provides an insight into the huge diversity of alkaliphilic bacteria, the varied products obtained from them, and the need for further investigations on these interesting bacteria.
