This book covers virtually all of the engineering science and technological aspects of separating water from particulate solids in the mining industry. It starts with an introduction to the field of mineral processing and the importance of water in mineral concentrators. The consumption of water in the various stages of concentration is discussed, as is the necessity of recovering the majority of that water for recycling. The book presents the fundamentals under which processes of solid-liquid separation are studied, approaching mixtures of discrete finely divided solid particles in water as a basis for dealing with sedimentation in particulate systems. Suspensions, treated as continuous media, provide the basis of sedimentation, flows through porous media and filtration. The book also considers particle aggregations, and thickening is analyzed in depth. Lastly, two chapters cover the fundamentals and application of rheology and the transport of suspensions.

This work is suitable for researchers and professionals in laboratories and plants, and can also serve as additional readingfor graduate seminars on solid liquid separation as well as for advanced undergraduate and graduate level studentsfor courses of fluid mechanics, solid-liquid separation, thickening, filtration and transport of suspensions in tubes and channels.

Thomas F Walsh tells the story of one of the West's wealthiest mining magnates -- an Irish American prospector and lifelong philanthropist who struck it rich in Ouray County, Colorado. In the first complete biography of Thomas Walsh, John Stewart recounts the tycoon's life from his birth in 1850 and his beginnings as a millwright and carpenter in Ireland to his tenacious, often fruitless mining work in the Black Hills and Colorado, which finally led to his discovery of an extremely rich vein of gold ore in the Imogene Basin. Walsh's Camp Bird Mine yielded more than $20 million worth of gold and other minerals in twenty years, and the mine's 1902 sale to British investors made Walsh very wealthy. He achieved national prominence, living with his family in mansions in Colorado and Washington DC, and maintaining a rapport with Presidents McKinley, Theodore Roosevelt, and Taft, as well as King Leopold II of Belgium. Despite his fame and lavish lifestyle, Walsh is remembered as an unassuming and philanthropic man who treated his employees well. In addition to making many anonymous donations, he established the Walsh Library in Ouray and a library near his Irish birthplace, and helped establish a research fund for the study of radium and other rare western minerals at the Colorado School of Mines. Walsh gave his employees at the Camp Bird Mine top pay and lodged them in an alpine boarding-house featuring porcelain basins, electric lighting, and excellent food. Stewart's engaging account explores the exceptional path of this Colorado mogul in detail, bringing Walsh and his time to life.

The future of mining in South Africa is hotly contested. Wide-ranging views from multiple quarters rarely seem to intersect, placing emphasis on different questions without engaging in holistic debate.

This book aims to catalyse change by gathering together fragmented views into unifying conversations. It highlights the importance of debating the future of mining in South Africa and for reaching consensus in other countries across the mineral-dependent globe.

It covers issues such as the potential of platinum to spur industrialisation, land and dispossession on the platinum belt, the roles of the state and capital in mineral development, mining in the era of the Fourth Industrial Revolution, the experiences of women in and affected by mining since the late 19th century and mine worker organising: history and lessons and how post-mine rehabilitation can be tackled.

It was inspired not only by an appreciation of South Africa’s extensive mineral endowments, but also by a realisation that, while the South African mining industry performs relatively well on many technical indicators, its management of broader social issues leaves much to be desired. It needs to be deliberated whether the mining industry can play as critical a role going forward as it did in the evolution of the country’s economy.

Provides case studies, commentary and analysis on the mining sector from international experts in business, across the four key focus areas of strategic, operational, financial and disclosure perspectives on mining. Invaluable to executives, managers and advisers involved in the mining sector, including public and private mining companies.

Some vanguard companies have evolved to a higher level of decentralization originating in the enabling-and-autonomy paradigm. A new kind of deep leadership is practiced by these spirit-driven organizations. This book brings together theory and case studies to cover historical origins and developments of both types of decentralization.

The Fly River and its tributaries, the Ok Tedi and Strickland rivers, are located in the Western Province of Papua New Guinea. All three rivers have their source in the rugged central mountain range of the island and eventually flow, via the Fly River delta, into the Gulf of Papua to the north of Australia's Great Barrier Reef. With a catchment area still largely covered by tropical rainforest and relatively few human inhabitants, this remote part of Papua New Guinea presents a rare opportunity to document and understand the dynamics of a large tropical river system largely unaffected by human activity.
In 1984 the Ok Tedi Mining Company Limited began mining copper and gold mineralisation from Mt. Fubilan, which is located at the headwaters of the Ok Tedi. In 1990, mining begin at the Porgera gold mine located at the headwaters of the Strickland River. Since that time both companies have intensely monitored the environment of the Fly River system in order to better understand the possible impact of mining.
This book is intended to assemble and summarise this vast amount of information, much of it contained in internal company reports, to better understand the environmental complexity and dynamics of this large and relatively undisturbed tropical river system.
The approach to be taken in achieving this outcome is to solicit contributions summarising each of the scientific disciplines to be covered from recognised experts with experience in the region.
* documents physical and biologic change in a large tropical river system brought about largely by mining in an otherwise pristine environment.
* this book brings together a broad rand of disciplines to provide acomprehensive overview of change in a complex and dynamical tropical river system based largely on previously unpublished company reports.
* the book provides examples of state-of-the-art strategies and methodologies for monitoring environmental impact in a large river system.

Challenging Canada's image as a humane, enlightened global actor, Colonial Extractions examines the troubling racial logic that underpins Canadian mining operations in several African countries. Drawing on colonial, postcolonial, and critical race theory, Paula Butler investigates Canadian mining activities and the discourses which serve to legitimate this work. Through a series of interviews with senior personnel of businesses with mining operations in Africa, Butler identifies a continuation of the same colonialist mindset that saw resource ownership and racial dominance over Indigenous peoples in Canada as part of Canada's nation-building project. Financially, culturally, and psychologically, Canadians are invested in extracting resource-based wealth in the Global South, and - as Butler's analysis of Canada's influence over South Africa's first post-apartheid mining legislation shows - they look to legitimize that extraction through neoliberal legal frameworks and a powerful national myth of benevolence. Complementing analyses of the industry through political economy or critical development studies, Colonial Extractions is a powerful and unsettling critique of the cultural dimension of Canada's mining industry overseas.

International institutions (United Nations, World Bank) and multinational companies have voiced concern over the adverse impact of resource extraction activities on the livelihood of indigenous communities. This volume examines mega resource extraction projects in Australia, Bolivia, Canada, Chad, Cameroon, India, Nigeria, Peru, the Philippines.

This manual explains the evolution of British coalmining from a technical and engineering standpoint from the 18th to the 20th century, the heyday of British mining. The book explains the history and technology both above and below ground, exploring the pit head surface machinery and the transportation networks that fed into it, and the personal kit and equipment of individual miners. It also looks at how successive generations of mining engineers have met the perennial challenges and dangers of mining: pressure from millions of tons of rock and earth above; water drainage; fire and gas explosions; roof and seam collapse; underground illumination; ventilation; disease and accidents.

The authors explore the complex dynamics of mining and Corporate Social Responsibility (CSR) in Latin America, including a reflection on the African continent, presenting arguments and case studies based on new research on a set of urgent and emerging questions surrounding mining, development and sustainability.

The global spread of transnational mining investment, which has been taking place since the 1990s, has led to often volatile conflicts with local communities. This book examines the regulation of these conflicts through national, transnational and local legal processes. In doing so, it examines how legal authority is being redistributed among public and private actors, as well as national and transnational actors, as a result of globalizing forces. The book presents a case study concerning the negotiation of land transfer and resettlement between a transnational mining enterprise and indigenous peasants in the Andes of Peru. The case study is used to explore the intensely local dynamics involved in negotiations between corporate and community representatives and the role played by legal ordering in these relations. In particular, the book examines the operation of a transnational legal regime managed by the World Bank to remedy the social and environmental impacts of projects which receive Bank assistance. The book explores the nature and character of the World Bank regime and the multiple consequences of this projection of transnational law into a local dispute.

Reserves Estimation for Geopressured Gas Reservoirs aims to introduce the principles and methods for calculating reserves of geopressured gas reservoirs with the material balance method, presenting advantages, disadvantages and applicable conditions of various methods. The book, based on manual analysis, explains methods and calculation steps with more than 30 gas reservoir examples. It will help gas reservoir engineers learn basic principles and calculation methods and familiarize themselves with the content of the software Black Box, which in turn helps improve the level of gas field performance analysis and the level of gas field development.

This book investigates the Upper Silesian Coal Basin (USCB), one of the oldest and largest mining areas not only in Poland but also in Europe. Using uniform research methods for the whole study area, it also provides a summary of the landscape transformations. Intensive extraction of hard coal, zinc and lead ores, stowing sands and rock resources have caused such extensive transformations of landscape that it can be considered a model anthropogenic relief. The book has three main focuses: 1) Identifying anthropogenic forms of relief related to mining activity and presenting them from a spatial, genetic and age perspective; 2) Determining the changes in the morphometric characteristics of relief and the conditions for matter circulation in open systems (drainage basins) and closed systems (land-locked basins) caused by the extraction of mineral resources; and 3) Estimating the extent of anthropogenic denudation using two different methods based on raw-material output and morphometric analysis. In Poland, no other mining area has undergone such intensive mining activity as the Upper Silesian Coal Basin during the last half century. Its share in the total extraction of mineral resources was as high as 32%. The total extraction of hard coal in the Upper Silesian Coal Basin from the mid-18th century until 2009 was the sixth largest in the world, and the permanent, regional effects of mining anthropopressure on the relief are among the most severe in the world. The anthropogenic denudation rate in the Upper Silesian Coal Basin, as well as the Ruhr Coal Basin (Ruhr District) and the Ostrava-Karvina Coal Basin, ranges from several dozen up to several hundred times higher than the rate of natural denudation, irrespective of the calculation method used. It would take the natural denudation processes tens of thousands of years to remove the same amount of material from the substratum as that removed through human mining activity.

Energy is central to the fabric of society. This book revisits the classic notions of energy impacts by examining the social effects of resource extraction and energy projects which are often overlooked. Energy impacts are often reduced to the narrow configurations of greenhouse gas emissions, chemical spills or land use changes. However, this neglects the fact that the way we produce, distribute and consume energy shapes society, political institutions and culture. The authors trace the impacts of contemporary energy and resource extraction developments and explain their significance for the shaping of powerful social imaginaries and a reconfiguration of political and democratic systems. They analyse not only the complex histories and landscapes of industrial mining and energy development, including oil, coal, wind power, gas (fracking) and electrification, but also their significance for contested energy and social futures. Based on ethnographic and interdisciplinary research from around the world, including case studies from Australia, Germany, Kenya, the Netherlands, Nicaragua, Norway, Poland, Turkey, UK and USA, they document the effects on local communities and how these are often transformed into citizen engagement, protest and resistance. This sheds new light on the relationship between energy and power, reflecting a wide array of pertinent impacts beyond the usual considerations of economic efficiency and energy security. The volume is aimed at advanced students and researchers in anthropology, sociology, human geography, science and technology studies, environmental studies and sustainable development as well as professionals working in the field of impact assessments.

The book presents an overview of the International practices and state-of-the-art of LCA studies in the agri-food sector, both in terms of adopted methodologies and application to particular products; the final purpose is to characterise and put order within the methodological issues connected to some important agri-food products (wine, olive oil, cereals and derived products, meat and fruit) and also defining practical guidelines for the implementation of LCAs in this particular sector. The first chapter entails an overview of the application of LCA to the food sector, the role of the different actors of the food supply chain and the methodological issues at a general level. The other chapters, each with a particular reference to the main foods of the five sectors under study, have a common structure which entails the review of LCA case studies of such agri-food products, the methodological issues, the ways with which they have been faced and the suggestion of practical guidelines.

This book provides comprehensive coverage on the key issues of Chinese investment in the Australian minerals industry. It offers unique insights into the entry process, the management of Chinese investments, and their success factors and lessons learnt as being impacted upon by the entangling of political, economic, social and competitive forces.

The authors explain why the discovery and development of natural resources is commonly associated with unstable and unequal development, and frequently with violence. They demonstrate the need for policies and institutions by reflecting on both successes and failures in case studies on Botswana, Nigeria and Niger as well as Bolivia, Chile and Peru.

Why did South African mines become renowned for mine safety, while the mounting rate of silicosis in black migrant workers lay hidden for over a century? How complicit were regulating officers in the operation of the gold mines' apartheid health and safety policies? Why and how was tuberculosis among black migrant miners not disclosed, perpetuating a cycle of disease (and death) and allowing the infection to spread to neighbouring states? This book reveals how the South African mining industry, abetted by a minority state, hid a pandemic of silicosis for almost a century, and allowed workers infected with tuberculosis to spread the potentially fatal disease to rural communities in South Africa and labour-sending states. The first crisis of 1896-1912 focused on the minority white workers and resulted in industry investing heavily on reducing dust levels. The second began in 2000 with mounting scientific evidence that the disease rate among black migrant miners is more than a hundred times higher than officially acknowledged. This has resulted in class actions against operating companies.

This book is a necessary resource for geophysicist working in the oil and gas and mineral exploration industries, as well as for students and academics in exploration geophysics.

Originating as a silver-mining camp and marketed today as a silver-mining ghost town, Calico, CA outlived the silver era when borax was discovered in its hills. Supplying Borax worldwide-employing the twenty mule teams still associated with Twenty-Mule Team Borax-the Calico mines played a pivotal role in the evolution of the less glamorous industry, borax mining. Correcting the image sold to tourists, Steeples provides a tight geographic, economic, social, political, and business history of Calico, a once thriving community struggling to survive in primitive conditions. He tells the tale of three Calicos: the silver-mining town, the borax-mining center, and the ghost town, providing a masterful history of regional silver mining and national borax mining, processing, and marketing. The book provides an essential chapter in the development of western mining, the borax industry, and western mining camps. But it is more than the story of silver and borax in Calico. Steeples probes beyond the mines and mills in search of the community's soul, considering, for instance, the local paper, the Calico Print, the creation of the twenty-mule team image of Borax, the entrepreneurship of Francis Marion Borax Smith and his multinational organization, the education of the children, and the creation of the modern-day myth. Contrasting the working Calico with the illusory Calico, Steeples writes the complete history of the town from its natural setting to its imaginary legacy.

With Asia as its backdrop, this book investigates the role played by the World Bank Group (WBG) in conceptualising and promoting new mining regimes tailored for resource-rich country clients. It details a particular politics of mining in the Global South characterised by the transplanting, hijacking and contesting of the WBG's mining agenda.

Mining's dramatic and dangerous nature is reflected in the hundreds of specialized tools and artifacts shown in over 500 color photographs and discussed in this revised and expanded second edition with updated pricing. Thirty categories, from advertising and assay equipment to surveying equipment and tokens, chronicle old mining methods in detail. An elevated appreciation is gained here of the men and women who spent part of their lives mining with this equipment. Today, historians and collectors pay respect to those people as they preserve and interpret the equipment that remains. This is an important and valuable reference for all concerned.

A Practical Guide to Piping and Valves for the Oil and Gas Industry covers how to select, test and maintain the right oil and gas valve. Each chapter focuses on a specific type of valve with a built-in structured table on valve selection. Covering both onshore and offshore projects, the book also gives an introduction to the most common types of corrosion in the oil and gas industry, including CO2, H2S, pitting, crevice, and more. A model to evaluate CO2 corrosion rate on carbon steel piping is introduced, along with discussions on bulk piping components, including fittings, gaskets, piping and flanges. Rounding out with chapters devoted to valve preservation to protect against harmful environments and factory acceptance testing, this book gives engineers and managers a much-needed tool to better understand today's valve technology.
