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.

Download or read book African Mining ’91 written by Institution of Mining and Metallurgy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second 'African Mining' conference is planned for June 1991, and follows the first, very successful, event held in May 1987. That full four-year period was characterized by substantial changes in the political and economic climate of many countries in both hemispheres. Copper prices were relatively firm, and the advance and steady demand for nickel and ferrochromium stabilized important sectors of the mineral industry, certainly in Zimbabwe. The promise for gold remained unfulfilled, but the smaller, relatively flexible, mines survived and only the large, deep and low-value mines seem seriously at risk. None of this has affected the hungry, and intensive exploitations from surface to the water-table have revealed many targets of promise to those willing to take the risks. The pattern in Southern Africa was extraordinarily stable among the turmoil, with independence for Namibia, adjustments in South Africa and a gradual shift to market economies in the region. The pace of exploration has increased to recover some part of the progress that was lost in the Independence struggle, and atthe end of the first decade in Zimbabwe, for example, oil is being sought in the Zambesi Rift, following the investigation of the Luangwa in Zambia, and there are exciting exploration projects for methane released from coal, deep in its basins.

Available in PDF, EPUB and Kindle. Book excerpt: The South African gold industry is approximately one hundred years old, and is still characterized by a dynamic spirit of research and innovation. With the apparently inexorable rise in the price of gold, even minor improvements in recovery or reductions in operating costs have major economic significance. Recent advances in metallurgical research and development include the following: (i) An electrochemical explanation for the gold-cementation process. This indicates why such large amounts of zinc - some twenty times the stoichiometric requirement - together with lead nitrate are necessary for the almost complete precipitation of gold from cyanide solution. (ii) Application of the carbon-in-pulp process to the direct extraction of dissolved gold from cyanidation pulps. Novel features include a technique for retaining the loaded granules of activated carbon against the pulp flow, a new technique for subsequent stripping of the gold from the carbon, and the development of a packed-bed electrode cell for electrowinning of the gold from the eluate. A solution to the problem of clogging in the ball matrix of wet high-intensity magnetic separators used for the beneficiation of Witwatersrand uranium-and-gold-bearing residues. The balls, which are in a carousel, are removed continuously through a side discharge, are cleaned, and are returned to the separator. (iv) The development of a powerful but compact centrifugal mill for the underground milling of Witwatersrand ores in deep mines so that the milled product can be concentrated and then pumped to the surface, the discard material being used as backfill in the excavation. The anticipated reduction in the amount of energy required to hoist low-grade ores through thousands of metres, together with a reduction in ventilation and supporting structures, promises to extend the lives of mines that have become too deep to be exploited economically with existing technology. (v) The large-scale reclamation of gold from tailings dumps. One example involves the retreatment of several mine dumps many kilometres apart at a central processing plant - the Ergo project. Apart from a plant handling 2100 tons of dump material per hour, housing 156 flotation cells (the majority of which are 14 000 litres in volume) and three tailings-thickener tanks each 138 metres in diameter, the production and transportation of the pulp is an impressive exercise.

Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1970s, the South African gold-mining industry, for decades dominated by a set of fixed and unchanging features, has undergone a transformation. Above all, it is in the area of labour relations that changes have been most rapid and profound. Faced with a crisis in traditional patterns of labour recruitment, the mines have been forced to revise their sourcing and recruiting strategies and in so doing have struck at the heart of the migrant labour system. At the same time, in an attempt to contain the crisis of control, the mines have, for the first time in a hundred years, permitted trade unions to organise among workers, and in consequence the National Union of Mineworkers (NUM) has emerged as a powerful force in the industry. These processes are the subject of Wilmot James's sociological and historical study of African mine workers, which provides the first major account in twenty years of labour in South Africa's gold industry. In his lucid and original analysis, based on material much of which was not previously available to researchers, Wilmot James traces the interlocking developments which have brought about a transformation in the gold industry, and relates these to wider processes of change in contemporary South African society.

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.
