Download or read book The Extractive Metallurgy of Gold written by John C. Yannopoulos and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of gold begins in antiquity. Bits of gold were found in Spanish caves that were used by Paleolithic people around 40,000 B.C. Gold is the "child of Zeus," wrote the Greek poet Pindar. The Romans called the yellow metal aurum ("shining dawn"). Gold is the first element and first metal mentioned in the Bible, where it appears in more than 400 references. This book provides the most thorough and up-to-date information available on the extraction of gold from its ores, starting with the miner alogy of gold ores and ending with details of refining. Each chapter con cludes with a list of references including full publication information for all works cited. Sources preceded by an asterisk (*) are especially recom mended for more in-depth study. Nine appendices, helpful to both students and operators, complement the text. I have made every attempt to keep abreast of recent technical literature on the extraction of gold. Original publications through the spring of 1989 have been reviewed and cited where appropriate. This book is intended as a reference for operators, managers, and designers of gold mills and for professional prospectors. It is also designed as a textbook for extractive metallurgy courses. I am indebted to the Library of Engineering Societies in New York, which was the main source of the references in the book. The assistance of my son, Panos, in typing the manuscript is gratefully acknowledged.

Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: Modification of conventional cyanidation processes are being investigated by the Bureau of Mines to develop more efficient methods of extracting silver values from mine wastes and low-grade and refractory ores. One technique developed involves the selective precipitation of silver as Ag2S from cyanide solutions followed by recovery of residual god values on activated carbon. Carbon-in-pulp cyanidation appears promising for processing slimy tailings with the development of an efficient technique for stripping silver from loaded carbon with alkaline ethanol solutions at ambient temperature and pressure. Salt roasting-cyanidation treatment of a refractory ore gave 88% silver extraction compared with 60% attained by conventional cyanidation. The chloridized calcine is amenable to percolation or heap leaching with dilute cyanide solution.

Book excerpt: The eight articles first appeared as volume 6 (no date) of Mineral processing and extractive metallurgy review. They review new methods of recovery for gold, and to some extent, silver, focus on the particular challenges of extraction from carbonaceous ores and from various sulfide-bearing ore, and the treatment of refractory gold ore, and discuss high-temperature and biological oxidation, high- temperature chlorination, and removing metals from leach liquor.

Available in PDF, EPUB and Kindle. Book excerpt: Mechanical activation of solids is a part of mechanochemistry, the science with a sound theoretical foundation exhibiting a wide range of potential application. Mechanical activation itself is an innovative procedure where an improvement in technological processes can be attained via a combination of new surface area and defects formation in minerals. Mechanical activation is of exceptional importance in extractive metallurgy and mineral processing and this area forms the topic of this book and is the result of more than twenty years of research and graduate teaching in the field. In pyrometallurgy, the mechanical activation of minerals makes it possible to reduce their decomposition temperatures or causes such a degree of disordering that the thermal activation may be omitted entirely. The potential mitigation of environmental pollutants is becoming increasingly important in this context. The lowering of reaction temperatures, the increase of the rate and amount of solubility, preparation of water soluble compounds, the necessity for simpler and less expensive reactors and shorter reaction times are some of the advantages of mechanical activation in hydrometallurgy. The environmental aspects of these processes are particularly attractive. Several industrial processes are examined and their flowsheets are presented as succesful of activation. In these processes, the introduction of a mechanical activation step into the technological cycle significantly modifies the subsequent steps. The book is designed for researchers, teachers, operators and students in the areas of extractive metallurgy, mineral processing, mineralogy, solid state chemistry and materials science.It will encourage newcomers to the mechanochemistry to do useful research and discover novel applications in this field.
