Biomining Technologies

This book describes emerging and established industrial processes of biomining technologies used for the recovery of metals of economic interest from, e.g. mineral ores, mining and electronic wastes using microbiological technologies. Multiple chapters focus on engineering design and operation of biomining systems. Several industrial case studies from China, Chile, Peru, Russia/Kazakhstan and Finland are included, which emphasises the practical approach of the book. The reader not only learns more about the biology, diversity and ecology of microorganisms involved in biomining processes, but also about microbial biomolecular and cultivation tools used in the biomining industry. Special emphasis is put on emerging biotechnologies enabling the use of biomining for recycling metals from e-wastes, waste streams and process waters. Finally, the future impacts and direction of biomining towards sustainability in a metal-demanding world are also highlighted. The book is aimed at an interdisciplinary audience involving operators and researchers working across disciplines including geology, chemical engineering, microbiology and molecular biology. This is reflected by the content of this book, as well as by its authors, who are all leading practitioners and authorities in their fields.

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.

This book will serve as a ready reckoner of contemporary information regarding municipal solid waste landfill biomining, treatment of landfill leachate and heavy metals in a single platform. The academicians, researchers, and students at master’s and doctoral levels will be able to understand the current trends in municipal solid waste landfill operations, which will help in augmenting their research. Construction of new landfills requires huge monetary investments, which can be avoided if old landfills were bio-mined for resources and the space can be re-used as new landfills. Landfill leachate is a hazardous waste which needs proper treatment that could generate value-added products such as clean energy and biofertilizers. In this book, each chapter would provide the background, methodology, and relevant calculations for sustaining landfill operations. Also, the case studies based on best practices in municipal solid waste landfilling are discussed in this book.

Proper waste disposal is still a serious concern worldwide. This book addresses various types of wastes such as industrial, agricultural, and municipal solid and liquid wastes, their generation, and the status of waste management in developed and developing countries. It discusses advanced green technologies used in harnessing energy and bioproducts from wastes such as electricity, biofuel, biopolymers, fertilizers, and chemicals without damaging the quality of the environment but rather creating a source that is an added value to the environment. Through many applications and case studies, this comprehensive book helps readers build a state-of-the-art knowledge on waste utilization and energy generation. FEATURES Provides a comprehensive, state-of-the-art coverage of waste management practices, their challenges, and solutions from a global perspective Discusses conceptual principles and practices of various green technologies that can be used to generate valuable products from waste and improve environmental quality Includes case studies from the United States and Japan, providing detailed explanations of advanced bioremediation technologies Takes a holistic approach to waste management and bioproducts recovery Offers an easy-to-understand and target-oriented approach that helps both students and professionals advance their knowledge in creating wealth from waste Written for undergraduate and graduate students taking courses in environmental biotechnology, environmental microbiology, non-conventional energy sources, waste treatment technologies, environmental waste utilization, energy, and environment taught in universities and colleges. The book can also be used by professionals and researchers at different levels in related fields.

Manganese Mining Microorganisms covers the latest amalgamation of the diversity of Mn biomining microorganisms, their biosolubilization mechanisms, and their role in natural manganese biogeochemical cycling.

This new book provides an in-depth view of the latest trends in green mining, along with mechanistic views of biomining and bio recovery processes for both academic (undergraduate, postgraduate, doctoral students and lecturers/researchers) and industrial readers. Highlights the microbial diversity involved in manganese bioleaching/biomining Includes ecological and metagenomic insights of mining environments Describes mechanism of manganese bioleaching/biomining Explores and illustrates case studies in mineral microbiology Reports recent developments and future trends in manganese biomining

Focusing on current and future uses of microbes as production organisms, this practice-oriented textbook complements traditional texts on microbiology and biotechnology. The editors have brought together leading researchers and professionals from the entire field of industrial microbiology and together they adopt a modern approach to a well-known subject. Following a brief introduction to the technology of microbial processes, the twelve most important application areas for microbial technology are described, from crude bulk chemicals to such highly refined biomolecules as enzymes and antibodies, to the use of microbes in the leaching of minerals and for the treatment of municipal and industrial waste. In line with their application-oriented topic, the authors focus on the "translation" of basic research into industrial processes and cite numerous successful examples. The result is a first-hand account of the state of the industry and the future potential for microbes in industrial processes. Interested students of biotechnology, bioengineering, microbiology and related disciplines will find this a highly useful and much consulted companion, while instructors can use the case studies and examples to add value to their teaching.

This textbook on Environmental Biotechnology not only presents an unbiased overview of the practical biological approaches currently employed to address environmental problems, but also equips readers with a working knowledge of the science that underpins them. Starting with the fundamentals of biotechnology, it subsequently provides detailed discussions of global environmental problems including microbes and their interaction with the environment, xenobiotics and their remediation, solid waste management, waste water treatment, bioreactors, biosensors, biomining and biopesticides. This book also covers renewable and non-renewable bioenergy resources, biodiversity and its conservation, and approaches to monitoring biotechnological industries, genetically modified microorganism and foods so as to increase awareness. All chapters are written in a highly accessible style, and each also includes a short bibliography for further research. In summary this textbook offers a valuable asset, allowing students, young researchers and professionals in the biotechnology industry to grasp the basics of environmental biotechnology.
