The gold processing industry is experiencing change. As free-milling and oxide ores become depleted, more complex polymetallic and refractory ores are being processed, coupled with increasing pressure for stricter environmental compliance. Recent years have also seen a steady reduction in mineral processing and metallurgy graduates and a gradual loss of older operating experience. A contribution to documenting current and future best practice in gold ore processing seems timely. The focus of this volume is on advances in current gold plant operation, from conception to closure; chapters also cover innovations at the bench and pilot-scale level that would be expected to find commercial application at some stage. Sufficient coverage is also given to the chemistry and engineering aspects. The general principle behind the structure of the volume is that of flowsheeting based on unit operations and applied to a mineralogical classification of gold ore types. From concept to closure, this book covers all unit operations, mineralogies and processes that are relevant to dealing with today's complex orebodies. Practical experience is vital to the successful development, operation and closure of any operation. The 42 chapters have been contributed by a total of 66 authors and co-authors who are experts from countries spanning the globe, and representing exhaustive practical knowledge covering many disciplines relevant to gold processing. * Current best practice as elucidated by a select panel of experts in the field * Innovations at the bench and pilot-scale level that would be expected to find commercial application at some stage * Mineralogical-based approach to flowsheeting

The Office of Industrial Technologies (OIT) of the U. S. Department of Energy commissioned the National Research Council (NRC) to undertake a study on required technologies for the Mining Industries of the Future Program to complement information provided to the program by the National Mining Association. Subsequently, the National Institute for Occupational Safety and Health also became a sponsor of this study, and the Statement of Task was expanded to include health and safety. The overall objectives of this study are: (a) to review available information on the U.S. mining industry; (b) to identify critical research and development needs related to the exploration, mining, and processing of coal, minerals, and metals; and (c) to examine the federal contribution to research and development in mining processes.

Better Understand the Connection between Microbiology and the Inorganic World Microbiology for Minerals, Metals, Materials and the Environment links chemical, metallurgical, and other metal inherent systems with microbes, and analyzes the interdependence between them. Specifically intended to underscore the importance of microbes in environmental remediation in the mining industries, this text offers a basic and conceptual understanding of the role of microbes, and provides an extensive exploration of microbiology and metals. Each chapter is written by experts from research, industry and academia. The authors expand on the whole scale of microbiology applications relevant to minerals, metal, material, and environment. They elicit the applications of microbes for metal extraction (including mechanisms and methods) from primary ores/minerals and mining wastes, biomining and related concepts of microbial diversity and various operations, and molecular biology of microbes involved in such systems (extremophiles). They also address in detail biohydrometallurgy, biomineralisation, bioleaching, biobeneficiation, biosynthesis, and bioremediation and other related areas. This book: Includes bacterial leaching, hybrid leaching, and biosynthesis related to different metals Covers recent developments in alternative procedures with the use of extremophiles and leaching bacteria Explains the imperative importance of bacteria in minerals and metals sector Addresses microbial interventions for waste cleanup and upgradation of minerals Compares existing processes with the new ones to elicit their importance Provides case studies on all respective topics by eminent researchers A resource for researchers, graduate students, and industry professionals involved in chemical/mining/metallurgical engineering/environmental science/microbiology, Microbiology for Minerals, Metals, Materials and the Environment skillfully explains the symbiotic relationship between microbiology and minerals-metals-materials, and utilizes experts from across the globe.
