Download or read book Metallurgical Applications of Bacterial Leaching and Related Microbiological Phenomena written by Lawrence Murr and published by Elsevier. This book was released on 2012-12-02 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallurgical Applications of Bacterial Leaching and Related Microbiological Phenomena is a collection of papers presented at the International Symposium on Metallurgical Applications of Bacterial Leaching and Related Microbiological Phenomena, held in New Mexico Institute of Mining & Technology, Socorro, New Mexico on August 3-5, 1977. This book is organized into three sections encompassing 26 chapters. Section I emphasizes the role of microorganisms in the kinetics of leaching and similar metallurgical processes by stimulating a strong interaction between microbiologists and metallurgists. This section also discusses the basic study of microorganisms, in the strictly microbiological aspects of metal extraction and attendant conversion kinetics, and in the practical, engineering aspects of extraction. Section II deals with the microbiological leaching of waste materials, such as fly ash, slags, and jarosite-type leach residues. This section also describes a microbiological process for the recovery of sulfur in its elemental form from sulfate and sulfuric acid-containing aqueous wastes that are to be released in the environment. A microbiological leaching process for the removal of inorganic sulfur contained in coal is also described in this section. Considerable chapters in Section III are devoted to the specific applications of bacterial leaching, the optimization of the leaching conditions, and process optimization based upon economic considerations. This section also examines the advantages of large-scale testing compared with laboratory-testing. Workers in the fields of microbiology, biophysics, biochemistry, mineral processing and preparation, extractive and/or chemical metallurgy, mining engineering, and many related disciplines, including chemical and bioengineering, will find this book invaluable.

Available in PDF, EPUB and Kindle. Book excerpt: The book emphasizes various aspects of processing secondary sources for recovery of uranium. The field of secondary resource processing is gaining ground over the last few years as it is eco-friendly, economical and in tune with the philosophy of sustainable development. The book is the first one of its type in the area and includes a succint and comprehensive description of related areas of ore mineralogy, resource classification, processing principles involved in uranium solubilisation followed by separation and safety aspects. The clear organisation and the carefully selected figures and tables makes the treatment invaluable for practising engineers, research workers and academic institutions.
Download or read book Mineral Solubilizing Microorganisms MSM and their Applications in Nutrient Bioavailability Bioweathering and Bioremediation Volume II written by Muhammad Zahid Mumtaz and published by Frontiers Media SA. This book was released on 2024-04-18 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioweathering is the dissolution of rocks and mineral substrates carried out by microorganisms along with mechanical and chemical processes. The application of bacteria in biomining is a biotechnological approach for the extraction and recovery of metals from ores. Microbes interact with minerals as a strategy to colonize and exploit habitats where the environmental parameters disadvantage other microorganisms and they demonstrate the capacity to scavenge critical elements with low bioavailability, such as iron and phosphorus. There is an ongoing need to improve soil fertility and crop production, particularly in dry places, to remediate toxic soils, and clean stone artworks and structures. A more complete understanding of the ecology of mineral weathering processes mediated by the microbiome may provide a significant opportunity for researchers to develop novel solutions to developing challenges in agriculture, the environment, and industry.

Download or read book Microbial Energy Conversion written by H. G. Schlegel and published by Elsevier. This book was released on 2013-10-22 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial Energy Conversion documents the proceedings of a seminar in Gottingen in October 1976. This book discusses the potential of microorganisms to use solar energy or convert biomass produced by solar energy in such a way that new microbial energy sources can supplement or partially replace conventional sources. This compilation reviews biomass production and elaborates on in detail the microbial processes that are involved in the conversion of the primary biomass—either freshly harvested or disposed of as waste—into energy sources that are similar to hydrogen, methane, propane, gasoline, Diesel oil, methanol, ethanol, or electricity. The microbial processes that contribute to the development of known energy resources, such as mining of low grade ores of copper, zinc, and uranium; reclamation of oil from oil shale; and recovery of conventional and heavy oil and gas, are also deliberated. This text likewise elaborates on the study of photosynthetic enzyme systems, hydrogenase, immobilization of enzymes and pigments on membranes, and construction of artificial photosynthetic units. This book is beneficial to students and researchers conducting work on microbial energy conversion.
Download or read book Metal Recovery from Electronic Waste Biological Versus Chemical Leaching for Recovery of Copper and Gold written by Arda Işildar and published by CRC Press. This book was released on 2018-10-30 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Waste electrical and electronic equipment (WEEE) generation is a global problem. Despite the growing awareness and deterring legislation, most of the WEEE is disposed improperly, i.e. landfilled or otherwise shipped overseas, and treated in sub-standard conditions. Informal recycling of WEEE has catastrophic effects on humans and the environment. WEEE contains considerable quantities of valuable metals such as base metals, precious metals and rare earth elements (REE). Metal recovery from WEEE is conventionally carried out by pyrometallurgical and hydrometallurgical methods. In this PhD research, novel metal recovery technologies from WEEE are investigated. Using acidophilic and cyanide-generating bacteria, copper and gold were removed from crushed electronic waste with removal efficiencies of 98.4 and 44.0%, respectively. The leached metals in solution were recovered using sulfidic precipitation and electrowinning separation techniques. Finally, a techno-economic assessment of the technology was studied. This research addresses the knowledge gap on two metal extraction approaches, namely chemical and biological, from a secondary source of metals. The essential parameters of the selective metal recovery processes, scale-up potential, techno-economic and sustainability assessment have been studied.
Download or read book Biomining written by Douglas E. Rawlings and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomining is the use of microorganisms in the recovery of metals from ores. During bioleaching, metals such as copper, nickel or zinc are oxidized through microbial action from the water-insoluble sulfide to the soluble sulfate forms. Although gold is inert to microbial action, microbes can also be used in gold recovery from certain types of ores because as they oxidize the ore, they open up its structure, thereby allowing a gold-solubilizing agent such as cyanide to penetrate the ore. The book describes several industrial bioleaching and biooxidation processes as well as the underlying theory and biology of the microbes involved.
