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: First published in 1983, this book provides a comprehensive view of gold and gold trading in its many facets, and identifies those sources of information that are important for an understanding of the world’s gold markets. The author looks first at gold’s changing role since 1960; in particular, the change from the fixed price to the present free market determination of price. The different forms the demand for gold takes – bullion, paper or in fabricated forms such as jewellery – are explained in detail. This is followed by an analysis of the supply side – new gold production and the circulation of existing old gold. The survey concludes with an assessment of the gold market and of gold prices now and in the future.
Download or read book 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 concept of a multistage fluidized-bed column for the treatment of unclarified solutions dates back to the mid-1950s. Mintek, then the National Institute for Metallurgy, started developmental work on a continuous ion-exchange contactor in 1968, which culminated in the installation of a demonstration NIMCIX plant for the recovery of uranium at the Blyvooruitzicht Gold Mine in 1976. A number of NIMCIX plants were subsequently erected, both in South Africa and abroad, for the recovery of uranium from unclarified liquors. This technology has now been successfully applied to the recovery of gold by the use of activated carbon. The work described in the paper was carried out on a pilot plant that incorporated a seven-stage NIMCIX column and a Zadra-type elution-electrowinning circuit. An interesting feature of the operation was the adjustment of the feed solution to a pH value between 7,5 and 7,8 to reduce fouling of the carbon by carbonate and to improve the loading of gold onto the carbon. The use of a NIMCIX column in place of a tank-cascade for the recovery of gold from unclarified solutions promises lower plant capital costs, which could enhance the viability of, for example, a low-grade heap-leaching operation.

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

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.
