Excerpt: ... tailings contained, and seldom as much as two ounces of gold." Prof. Raymond's Report, 1870, page 364: --"It is impossible to state accurately what percentage of gold is lost in milling, as few assays are made either of the crude ore or of the tailings; but that a very large amount is lost can.not be doubted, and this loss probably varies from thirty to seventy per cent., according to the nature of the ore. None of the silver is saved except a small quantity, which being obtained in the gold, merely diminishes the value of the latter metal." Fossett's Colorado, page 292: --"It is estimated that more gold has been wasted in milling and has been washed down the creeks and gulches than has been saved." Albert Reiehenecker see Appendix, page 80 et seq). "The proportion of gold saved on the plates and tables varies, in a well-constructed mill, between thirty and fifty per cent. of the whole amount of gold in the quartz, and may average forty per cent." Article XII. THE PRESENT CONDITION OF INDUSTRIAL GOLD MINING. It will be apparent from these brief outlines that gold mining as an industrial pursuit encompasses interests of immense importance when the whole field of enterprise is brought into Tiew. The sources of the metal are practically beyond the measure of any method of calculation. The great extent of mineral area, the cosmical profusion displayed in nature with reference to all deposits of useful metals and substances, the expansive surface exploited and depths attained by practical working in widely-varying and separated localities, all tend to demonstrate the number and magnitude of workable veins of gold. In connection with this, it is also apparent that great progress has.been made in structural and...

Download or read book Global Gold Production Touching Ground written by Boris Verbrugge and published by Springer Nature. This book was released on 2020-05-04 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, gold mining has moved into increasingly remote corners of the globe. Aside from the expansion of industrial gold mining, many countries have simultaneously witnessed an expansion of labor-intensive and predominantly informal artisanal and small-scale gold mining. Both trends are usually studied in isolation, which contributes to a dominant image of a dual gold mining economy. Counteracting this dominant view, this volume adopts a global perspective, and demonstrates that both industrial gold mining and artisanal and small-scale gold mining are functionally integrated into a global gold production system. It couples an analysis of structural trends in global gold production (expansion, informalization, and technological innovation) to twelve country case studies that detail how global gold production becomes embedded in institutional and ecological structures.

Download or read book African Gold written by Roman Grynberg and published by Springer Nature. This book was released on 2021-04-22 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book explores the evolving economics of gold as a global commodity as well as the production and trade of gold in and from the African continent. The growth of gold as an increasingly important and diverse source of African wealth is examined, alongside the impact that the rise of China in the 21st century has had on the demand for gold. The volatility of the gold price has increased as a result of the dramatic decline of gold demand for manufacturing purposes. Gold is Africa’s second largest export after oil and is a perfect metaphor for a continent rich in resources while so much of its population lives in such dire poverty. The artisanal and small scale gold mining (ASGM) sector, is surprisingly widely perceived as being beneficial to the development of Africa despite its exploitation and dreadful health and environmental consequences. African Gold: Production, Trade and Economic Development considers policy issues regarding the gold mining sector, the economics of beneficiation, the retreat of jewelry manufacturing across the continent as well as ‘Africa’s golden future’. It is a relevant book for both academics and policymakers interested in Africa, natural resource, and development economics.

Available in PDF, EPUB and Kindle. Book excerpt: THE INDUSTRY THAT FORGED THE MODERN WORLD Throughout history metals and raw materials have underpinned human activity. So it is that the industry responsible for extracting these materials from the ground - mining - has been ever present throughout the history of civilisation, from the ancient world of the Egyptians and Romans, to the industrial revolution and the British Empire, and through to the present day, with mining firms well represented on the world's most important stock indexes including the FTSE100. This book traces the history of mining from those early moments when man first started using tools to the present day where metals continue to underpin economic activity in the post industrial age. In doing so, the history of mining methods, important events, technological developments, the important firms and the sparkling personalities that built the industry are examined in detail. At every stage, as the history of mining is traced from 40,000BC to the present day, the level of detail increases in accordance with the greater social and industrial developments that have played out as time has progressed. This means that a particular focus is given to the period since the industrial revolution and especially the 20th century. A look is also taken into the future in an effort to chart the direction this great industry might take in years to come. Many books have been written about mining; the majority have focused on a particular metal, geographical area, mining event or mining personality, but 'The History of Mining' has a broader scope and covers all of these essential and fascinating areas in one definitive volume.

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 1076 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
