This book was released on 2010-09-15 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Flotation Reagents: Chemistry, Theory and Practice: Flotation of Gold, PGM and Oxide Minerals, Volume 2 focuses on the theory, practice, and chemistry of flotation of gold, platinum group minerals (PGMs), and the major oxide minerals, along with rare earths. It examines separation methods whose effectiveness is limited when using conventional treatment processes and considers commercial plant practices for most oxide minerals, such as pyrochlore-containing ores, copper cobalt ores, zinc ores, tin ores, and tantalum/niobium ores. It discusses the geology and mineralogy of gold, PGMs, and oxide minerals, as well as reagent and flotation practices in beneficiation. The book also looks at the factors affecting the floatability of gold minerals and describes PGM-dominated deposits such as Morensky-type deposits, hydrothermal deposits, and placer deposits. In addition, case studies of flotation and beneficiation in countries such as Canada, Africa, Russia, Chile, and Saudi Arabia are presented. This book will be useful to researchers, university students, and professors, as well as mineral processors faced with the problem of beneficiation of difficult-to-treat ores. - Looks at the theoretical aspects of flotation reagents - Examines the practical aspects of using chemical reagents in operating plants - Provides guidelines for researchers and engineers involved in process design and development

Available in PDF, EPUB and Kindle. Book excerpt: New discoveries of the properties of gold at a nanoscale, and its effective use in modern technologies, have been driving a virtual 'gold rush'. Depleting natural resources has meant that the recovery of gold continues to grow in importance and relevance.The Recovery of Gold from Secondary Sources analyses the most advanced technology in gold recovery and recycling from spent sources of mobile phones, unwanted electronic equipment and waste materials. State-of-the-art techniques of hydrometallurgical and bio-metallurgical processing, leaching, cementing, adsorbing and separation through bio-sorbents are all described in detail, providing a guide for students and researchers. Discussion of environmentally friendly methods of recovery are presented, in order to provide modern-day alternatives to previous techniques. For those interested in the study of gold recovery this book gives a comprehensive overview of current recovery, making it the ultimate source of information for students, researchers, chemists, metallurgists, environmental scientists and electronic waste recovery experts.

Download or read book Au gold Recovery Using an Activated Carbon Column written by and published by . This book was released on 1986 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of a process involving the use of activated carbon in a multi-stage column (NIMCIX contactor) for the recovery of gold from unclarified pregnant solutions was investigated on pilot-plant scale. It was found that satisfactory extractions, corresponding to a recovery of 99,6 per cent, can be achieved with an average gold concentration of 0,0077 p.p.m. in the barren solutions from a feed averaging 1,89 p.p.m. The results show that excessive loading of CaCO3 can be prevented by lowering of the pH of the feed to about 7,6. This obviates the need for the carbon to be treated with hydrochloric acid. The gold was eluted from the carbon by the Zadra procedure. The operating conditions of the elution and electrowinning circuits are reported, and the elution of the gold and other metals is discussed. The reactivation of the carbon, which was carried out in a vibrating-deck kiln, is described, and the effects of this reactivation on the activity of the carbon and its microstructure are also discussed. The consumption of reagents in the adsorption and elution circuits is presented in sufficient detail to allow the potential of the activated-carbon process as an alternative to the Merill-Crowe process for the treatment of high-grade solutions to be evaluated. In addition, the results of parallel small-scale investigations on the effect of pH on the loading of CaCO3, gold, and other metals on activated carbon are presented and discussed briefly.

Book excerpt: There is a considerable challenge in maximising gold flotation (recovery and grade) in relation to copper flotation in porphyry copper-gold ores. This is due to differences in mineralogy, surface chemistry and morphology between gold and copper-bearing minerals. This is further complicated by the choice of reagents (e.g. collector) for Au due to the varying nature of Au particles (both native and electrum) in these ores. It is therefore imperative that optimising gold flotation recovery requires accurate and diagnostic mineralogical and surface characterisation to understand its occurrence, liberation and associations with both the host and gangue minerals. The trace and fine-sized nature of Au particles in these ores make mineralogical and surface characterisation difficult and, thus, also a challenge. In this thesis, mineralogical and surface analytical techniques together with flotation strategies (different collector regimes, regrinding and pyrite depression), were used to maximise Au flotation in a typical porphyry copper-gold without detrimental effect on Cu recoveries and rejecting significant pyrite.

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.
