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.

Book excerpt: Some recent work on the recovery of gold from refractory gold- bearing materials is described, special reference being made to some deposits in southern Africa. Possible explanations for the poor response of some gold-bearing materials to cyanidation are summarized, and the results of investigations into four techniques to enhance the response of refractory gold-bearing materials to cyanidation are presented. Mineralogical examinations of the feed and solid residues are used to show the reasons for the results obtained. Compared to conventional cyanide leaching, cyanidation under elevated pressure and lowered alkalinity significantly enhanced the rate of gold dissolution but, for all the samples except a stibnite concentrate, which gave a significantly better result, the final gold extraction showed no improvement. Activated carbon was deactivated, i.e. deprived of its ability to adsorb dissolved gold, by the addition of organic reagents. However, attempts similarly to poison the carbonaceous material in a sample of gold-bearing dump material were unsuccessful. Gold dissolution was enhanced by the oxidation of pyrite and arsenopyrite to sulphuric acid and aqueous ferric and arsenic species prior to cyanidation of the solid residue. A process comprising pyrolysis, mild oxidative leaching, the removal of elemental sulphur, and cyanidation gave gold dissolutions of up to 99 per cent, i.e. significantly better than by any other process.

Download or read book Advances in Gold Ore Processing written by Mike D. Adams and published by Elsevier. This book was released on 2005-12-02 with total page 1077 pages. 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

Download or read book The Extractive Metallurgy of Gold written by John C. Yannopoulos and published by Springer. This book was released on 1991 with total page 304 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.
