Microbial Processing Of Metal Sulfides

The application of microbiological methods to the extraction of metals from minerals is supported by several bioleaching and biooxidation processes operating in different sites over the world. This book details the basic aspects of the process with special emphasis on recent contributions regarding the chemical and microbial aspects of the bioleaching process and the use of microorganisms in the treatment of complex ores and concentrates.

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.

Although many available metal recycling methods are simple and fast, they are also expensive and cause environmental pollution. Biohydrometallurgical processing of metals offers an alternative to overcome these issues, as the use of biological means not only helps to conserve dwindling ore resources but also fulfills the need for the unambiguous need to extract metals in nonpolluting, low-energy, and low-cost way. This book covers biohydrometallurgy and its application in the recovery of metals from secondary sources like wastes. It aims to provide readers with a comprehensive overview of different wastes for metal recovery and biological treatment methods that are both environmentally friendly and economically viable.

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 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.

Proper waste disposal is still a serious concern worldwide.
