The aim of process calculations is to evaluate the performance of minerals and coal processing operations in terms of efficiency of the operation, grade of the final products and recovery of the required constituents. To meet these requirements, in-depth detailed calculations are illustrated in this book. This book is designed to cover all the process calculations. The method and/or steps in process calculations have been described by taking numerical examples. Process calculations illustrated in a simple and self explanatory manner based on two basic material balance equations will allow the reader to understand the contents thoroughly. Inclusion of elaborate process calculations in every chapter is the highlight of this book. This book is unique and devoted entirely to the process calculations with sufficient explanation of the nature of the calculations. This book will prove useful to all: from student to teacher, operator to engineer, researcher to designer, and process personnel to plant auditors concerned with minerals and coal processing.

In 2006, UNESCO designated Cornwall and West Devon Mining Landscape a World Heritage Site. In the eighteenth century, Cornwall was one of the country's principal industrial areas. Before the late 1870s, it produced more tin than any other region in the world, and in the early nineteenth century its output of copper was two-thirds of world production. The remains of the mines contribute to a distinctive cultural landscape; more than 200 engine houses survive - the largest concentration of such monuments in the world. This book, and its companion Cornish Mines: St Just to Redruth, is a guide to the best examples of the surviving mines, with stunning photographs and authoritative text.

Africa supplies the majority of the world's diamonds, yet consumers generally know little about the origins and history of these precious stones beyond sensationalized media accounts of so-called blood diamonds.
"Stones of Contention" explores the major developments in the remarkable history of Africa's diamonds, from the first stirrings of international interest in the continent's mineral wealth in the first millennium A.D. to the present day. In the European colonial period, the discovery of diamonds in South Africa ushered in an era of unprecedented greed during which monopolistic enterprises exploited both the mineral resources and the indigenous workforce. In the aftermath of World War II, the governments of newly independent African states, both democratic and despotic, joined industry giant De Beers and other corporations to oversee and profit from mining activity on the continent.
The book also considers the experiences of a wide array of Africans--from informal artisanal miners, company mineworkers, and indigenous authorities to armed rebels, mining executives, and premiers of mineral-rich states--and their relationships to the stones that have the power to bring both wealth and misery. With photos and maps, Stones of Contention illustrates the scope and compexity of the African diamond trade as well as its impact on individuals and societies.

"I realize that I am a soldier of production whose duties are as important in this war as those of the man behind the gun." So began the pledge that many home-front men took at the outset of World War II when they went to work in the factories, fields, and mines while their compatriots fought in the battlefields of Europe and on the bloody beaches of the Pacific. The male experience of working and living in wartime America is rarely examined, but the story of these men provides a crucial counter narrative to the national story of Rosie the Riveter and GI Joe that dominates scholarly and popular discussions of World War II. In "Meet Joe Copper", Matthew L. Basso describes the formation of a powerful, white, working-class masculine ideology in the decades prior to the war, and shows how it thrived - on the job, in the community, and through union politics. Basso recalls for us the practices and beliefs of the first- and second-generation immigrant copper workers of Montana while advancing the historical conversation on gender, class, and the formation of a white ethnic racial identity. "Meet Joe Copper" provides a context for our ideas of postwar masculinity and whiteness and finally returns the men of the home front to our reckoning of the Greatest Generation and the New Deal era.

In this volume in the NBER series on capital formation and financing, the authors show, with supporting figures, two major trends in mining and manufacturing. The first is that this sector had a rate of growth significantly higher than that of the economy as a whole. The total capital assets of this sector increased fifteenfold from 1880 to 1948, while the total stock of all tangible wealth in the United States increased only about sixfold. The second trend is a marked diversity among industries in the rate of growth over the period and in the time pattern of that rate. The authors advance a number of explanatory hypotheses about the significance of their findings. Originally published in 1960.

In Saskatchewan, politics and potash are continuously, inextricably intertwined. The province is the largest single producer of potash on earth, accounting for about a quarter of the world's total production. The industry has played a significant role in the provincial economy for over 40 years and continues to contribute to Saskatchewan's growth. Recoverable reserves of potash are well over 100 billions tons. With global markets currently in upheaval, Potash explores the interface between politics and the industry, the question of returns to the people of the province, and considers new developments that portend changes to the existing state of affairs. Written by an insider who helped nationalise the industry in the 1970s, John Burton expertly integrates behind-the-scenes accounts of the major players, archival material, and interview sources to produce a book that cuts through the bull and adds to our understanding of the world's greatest fertiliser.

What are corporations, and to whom are they responsible? Anthropologist Marina Welker draws on two years of research at Newmont Mining Corporation's Denver headquarters and its Batu Hijau copper and gold mine in Sumbawa, Indonesia, to address these questions. She shows how, against the backdrop of an emerging Corporate Social Responsibility movement and changing state dynamics in Indonesia, people enact the mining corporation in multiple ways: as an ore producer, employer, patron, promoter of sustainable development, religious sponsor, auditable organization, foreign imperialist, and environmental threat. Rather than assuming that corporations are monolithic, profit-maximizing subjects, Welker turns to anthropological theories of personhood to develop an analytic model of the corporation as an unstable collective subject with multiple authors, boundaries, and interests. Enacting the Corporation demonstrates that corporations are constituted through continuous struggles over relations with--and responsibilities to--local communities, workers, activists, governments, contractors, and shareholders.

The history of mining is replete with controversy of which much is related to environmental damage and consequent community outrage. Over recent decades, this has led to increased pressure to improve the environmental and social performance of mining operations, particularly in developing countries. The industry has responded by embracing the ideals of sustainability and corporate social responsibility. Mining and the Environment identifies and discusses the wide range of social and environmental issues pertaining to mining, with particular reference to mining in developing countries, from where many of the project examples and case studies have been selected. Following an introductory overview of pressing issues, the book illustrates how environmental and social impact assessment, such as defined in "The Equator Principles", integrates with the mining lifecycle and how environmental and social management aims to eliminate the negative and accentuate the positive mining impacts. Practical approaches are provided for managing issues ranging from land acquisition and resettlement of Indigenous peoples, to the technical aspects of acid rock drainage and mine waste management. Moreover, thorough analyses of ways and means of sharing non-transitory mining benefits with host communities are presented to allow mining to provide sustainable benefits for the affected communities. This second edition of Mining and the Environment includes new chapters on Health Impact Assessment, Biodiversity and Gender Issues, all of which have become more important since the first edition appeared a decade ago. The wide coverage of issues and the many real-life case studies make this practice-oriented book a reference and key reading. It is intended for environmental consultants, engineers, regulators and operators in the field and for students to use as a course textbook. As much of the matter applies to the extractive industries as a whole, it will also serve environmental professionals in the oil and gas industries. Karlheinz Spitz and John Trudinger both have multiple years of experience in the assessment of mining projects around the world. The combination of their expertise and knowledge about social, economic, and environmental performance of mining and mine waste management has resulted in this in-depth coverage of the requirements for responsible and sustainable mining.

Disputes and dispossession of property rights in the mining sector are causes of injustice, violence, and forced resettlement around the world. This comprehensive volume examines mining, particularly what is often called 'Artisanal and Small-Scale Mining', from a perspective of governance and rights. It focuses on rights to land, natural resources, and other forms of material 'property'. Many projects, policies, and laws targeting artisanal and small-scale mining are embedded in problematic conceptual and institutional frameworks that implicitly stigmatise and discipline artisanal and small-scale miners. This collection takes a critical look at notions of property to destabilise some of these frameworks. The chapters in this book are notable for their recognition of the agency of artisanal miners and 'local communities' within the uneven hierarchies in which they are embedded, and their acknowledgement of the difficulties of state regulation of such a complex set of issues. The authors use a variety of theoretical tools, engaging with political economy, political ecology, classical economic theory, and socio-cultural concepts derived from ethnographic methods. This book includes insightful case studies from Colombia, Democratic Republic of Congo, Ghana, Mongolia, South Africa, and Zambia, and is an important resource for academics, development practitioners, and policy-makers. It was originally published online as a special issue of Third World Thematics.

This book provides construction professionals, designers, contractors and quality auditors involved in construction projects with the auditing skills and processes required to improve construction quality and make their projects more competitive and economical. The processes within the book focus on auditing compliance to ISO, corporate quality management systems, project specific quality management systems, contract management, regulatory authorities' requirements, safety, and environmental considerations. The book is divided into seven chapters and each chapter is divided into numbered sections covering auditing-related topics that have importance or relevance for understanding quality auditing concepts for construction projects. No other book covers construction quality auditing in such detail and with this level of practical application. It is an essential guide for construction and quality professionals, but also for students and academics interested in learning about quality auditing in construction projects.

Surface and Underground Excavations - Methods, Techniques and Equipment (2nd edition) covers the latest technologies and developments in the excavation arena at any locale: surface or underground. In the first few chapters, unit operations are discussed and subsequently, excavation techniques are described for various operations: tunnelling, drifting, raising, sinking, stoping, quarrying, surface mining, liquidation and mass blasting as well as construction of large subsurface excavations such as caverns and underground chambers. The design, planning and development of excavations are treated in a separate chapter. Especially featured are methodologies to select stoping methods through incremental analysis. Furthermore, this edition encompasses comprehensive sections on mining at 'ultra depths', mining difficult deposits using non-conventional technologies, mineral inventory evaluation (ore - reserves estimation) and mine closure. Concerns over Occupational Health and Safety (OHS), environment and loss prevention, and sustainable development are also addressed in advocating a solution to succeed within a scenario of global competition and recession. This expanded second edition has been wholly revised, brought fully up-to-date and includes (wherever feasible) the latest trends and best practices, case studies, global surveys and toolkits as well as questions at the end of each chapter. This volume will now be even more appealing to students in earth sciences, geology, and in civil, mining and construction engineering, to practicing engineers and professionals in these disciplines as well as to all with a general or professional interest in surface and underground excavations.

Mining activities may result in rock mass deterioration and instability that may lead to failure both in underground and open pit mines. Such deterioration represents a safety risk and may result in substantial financial losses. Rock mass response may lead to ground subsidence, fall of ground/caving, inundation, pillar collapse, seismic activities and slope and tailings dam instability. Each response is preceded by warning signs and precursors, which are identified in this book, with a view to providing guidelines for prediction and amelioration of damage to mining structures. Furthermore, case studies of both large scale ground deterioration leading to collapse and geotechnical mine disasters are presented. Identifying risks and monitoring geotechnical precursors and warning signs allows for safe and productive mining.

Like an old-fashioned hymn sung in rounds, Something's Rising gives a stirring voice to the lives, culture, and determination of the people fighting the destructive practice of mountaintop removal in the coalfields of central Appalachia. Each person's story, unique and unfiltered, articulates the hardship of living in these majestic mountains amid the daily desecration of the land by the coal industry because of America's insistence on cheap energy. Developed as an alternative to strip mining, mountaintop removal mining consists of blasting away the tops of mountains, dumping waste into the valleys, and retrieving the exposed coal. This process buries streams, pollutes wells and waterways, and alters fragile ecologies in the region. The people who live, work, and raise families in central Appalachia face not only the physical destruction of their land but also the loss of their culture and health in a society dominated by the consequences of mountaintop removal. Included here are oral histories from Jean Ritchie, "the mother of folk," who doesn't let her eighty-six years slow down her fighting spirit; Judy Bonds, a tough-talking coal-miner's daughter; Kathy Mattea, the beloved country singer who believes cooperation is the key to winning the battle; Jack Spadaro, the heroic whistle-blower who has risked everything to share his insider knowledge of federal mining agencies; Larry Bush, who doesn't back down even when speeding coal trucks are used to intimidate him; Denise Giardina, a celebrated writer who ran for governor to bring attention to the issue; and many more. The book features both well-known activists and people rarely in the media. Each oral history is prefaced with a biographical essay that vividly establishes the interview settings and the subjects' connections to their region. Written and edited by native sons of the mountains, this compelling book captures a fever-pitch moment in the movement against mountaintop removal. Silas House and Jason Howard are experts on the history of resistance in Appalachia, the legacy of exploitation of the region's natural resources, and area's unique culture and landscape. This lyrical and informative text provides a critical perspective on a powerful industry. The cumulative effect of these stories is stunning and powerful. Something's Rising will long stand as a testament to the social and ecological consequences of energy at any cost and will be especially welcomed by readers of Appalachian studies, environmental science, and by all who value the mountain's majesty -- our national heritage.

This book explores the formation of small and medium-sized construction company's (SME) compliance with health and safety issues in developing countries. Little has been written about the formation of SME contractors' health and safety compliance for developing countries, especially, in the sub-sahara regions where construction and infrastructure development activities have significantly increased in order to serve the development mandate of those countries. Thus, this book will provides insight into construction safety for SMEs, as well as health and safety compliance, and its policy implementation trends and development.

The digging of mineral wealth from the ground dates to prehistoric times, and Europeans pursued mining in the Americas from the earliest colonial days. Prior to the Civil War, very little mining went deep enough to require maps. However, the major finds of the mid-nineteenth century, such as the Comstock Lode, were vastly larger and deeper than any previous finds in America. Nystrom argues that, as industrial mining came of age in the United States, the development of maps and models gave power to a new visual culture. These maps and models became necessary tools in creating and controlling the mines' pitch-dark, three-dimensional space. Nystrom demonstrates that these neglected artifacts of the nineteenth and early twentieth centuries have much to teach us today.

Weak rocks encountered in open pit mines cover a wide variety of materials, with properties ranging between soil and rock. As such, they can provide a significant challenge for the slope designer. For these materials, the mass strength can be the primary control in the design of the pit slopes, although structures can also play an important role. Because of the typically weak nature of the materials, groundwater and surface water can also have a controlling influence on stability. Guidelines for Open Pit Slope Design in Weak Rocks is a companion to Guidelines for Open Pit Slope Design, which was published in 2009 and dealt primarily with strong rocks. Both books were commissioned under the Large Open Pit (LOP) project, which is sponsored by major mining companies. These books provide summaries of the current state of practice for the design, implementation and assessment of slopes in open pits, with a view to meeting the requirements of safety, as well as the recovery of anticipated ore reserves. This book, which follows the general cycle of the slope design process for open pits, contains 12 chapters. These chapters were compiled and written by industry experts and contain a large number of case histories. The initial chapters address field data collection, the critical aspects of determining the strength of weak rocks, the role of groundwater in weak rock slope stability and slope design considerations, which can differ somewhat from those applied to strong rock. The subsequent chapters address the principal weak rock types that are encountered in open pit mines, including cemented colluvial sediments, weak sedimentary mudstone rocks, soft coals and chalk, weak limestone, saprolite, soft iron ores and other leached rocks, and hydrothermally altered rocks. A final chapter deals with design implementation aspects, including mine planning, design implementation, monitoring, surface water control and closure of weak rock slopes. Key Features: Illustration of the best practice in modern open pit mines State of the art approaches for challenging designs Use of numerous case histories written by large-open pit operators to illustrate state of practice Individual chapters/sections written by leaders in the industry As with the other books in this series, Guidelines for Open Pit Slope Design in Weak Rocks provides guidance to practitioners involved in the design and implementation of open pit slopes, particularly geotechnical engineers, mining engineers, geologists and other personnel working at operating mines.

A Colorado favorite, Tomboy Bride presents the first-hand account of a young pioneer woman and her life in a rough and tumble mining town of the Old West. In 1906 at the age of twenty, Harriet Fish hopped on a train from Oakland, California, to the San Juan Mountains of Colorado in search of a new life as the bride of assayer George Backus. Together, the couple ventured forth to discover mining town life at the turn of the twentieth century, adjusting to dizzying elevation heights of 11,500 feet and all the hardships that come with it: limited water, rationed food supplies, lack of medical care, difficulty in travel, avalanches, and many more. As she and George move from Telluride’s Tomboy Mine to the rugged coast of British Columbia, to the town of Elk City, Idaho, and then back to Colorado’s Leadville, Harriet paints a poignant picture of a world centered around mining, sharing amusing and often challenging experiences as a woman of the era. With a new foreword by award-winning author Pam Houston, this 50th anniversary edition also includes previously unpublished black and white photographs documenting Harriet's journey. Tomboy Bride endures as a classic of the region to this day as it captures in heart-felt emotion and vivid detail the personal account of Harriet Backus, a true pioneer of the West.

Examines the silicosis crisis in the South African mining industry, and reveals how the rate of, often fatal, tuberculosis among black migrant miners was hidden for over a century. South Africa's gold mines are the largest and historically among the most profitable in the world. Yet at what human cost? This book reveals how the mining industry, abetted by a minority state, hid a pandemic of silicosis for almost a century and allowed miners infected with tuberculosis to spread disease to rural communities in South Africa and to labour-sending states. In the twentieth century, South African mines twice faced a crisis over silicosis, which put its workers at risk of contracting pulmonary tuberculosis, often fatal. The first crisis, 1896-1912, saw the mining industry invest heavily in reducing dust and South Africa became renowned for its mine safety. The second began in 2000 with mounting scientific evidence that the disease rate among miners is more than a hundred times higher than officially acknowledged. The first crisis also focused upon disease among the minority white miners: the current crisis is about black migrant workers, and is subject to major class actions for compensation.

In a fast-changing world, where the extraction of natural resources is key to development, whilst also creating environmental and social disasters, understanding how landscapes, people and politics are shaped by extraction is crucial. Looking at resource extraction in numerous locations at different stages of development, including North, West and South Africa, India, Kazakhstan and Australia, a broad picture is created, covering coal, natural-gas, gold and cement mining, from corporate to 'artisanal' extraction, from the large to the small scale. The chapters answer the questions: What is ideological about resource extraction? How does extraction transform the physical landscape? And how does the extractive process determine which stakeholders become dominant or marginalised? Contributing to policy debates, Mining Encounters uncovers the tensions, negotiations and disparities between different actors in the extractive industries, including exploiters and those who benefit or are impoverished by resource exploitation.

On a warm spring day in June of 1914, two hundred and thirty-five men went down into the depths of the Hillcrest mine found in Albertas Crowsnest Pass. Only forty-six would make it out alive. The largest coal-mining disaster in Canadian history, the fateful tale of the Hillcrest Mine is finally captured in startling detail by Stephen Hanon. A deft examination of the coal mining industry in an Alberta just on the cusp of the Great War, The Devils Breath is a startling recollection of heroism and human courage in the face of overwhelming calamity. Hanon examines the history of the mine itself, its owners and workers, possible causes for the disaster and the lasting effects that it had on those who lived, while educating readers on the techniques used to wrench coal from the bowels of the earth.

This book deals with 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.

Underground coal mining disturbs both the overburden strata and the immediate floor strata. The subject of surface subsidence deals with the issues associated with the movement of overburden strata, which are the layers from the seam to the surface, where structures and water resources important to human activities are located. Surface Subsidence Engineering provides comprehensive coverage of the major issues associated with surface subsidence. The chapters are written by experts on surface subsidence in the three leading coal producing and consuming countries in the world: Australia, China and the United States. They discuss general features and terminologies, subsidence prediction, subsidence measurement techniques, subsidence impact on water bodies, subsidence damage, mitigation and control, and subsidence on abandoned coal mines. In addition, the final chapter addresses some of the unique features of surface subsidence found in Australian coal mines. The book provides information on coal seams ranging from flat to gently inclined to steep to ultra-steep seams. Written for mining engineers, geotechnical engineers and students of mining engineering, this book covers both theories and practices of surface subsidence. Unlike previous publications, it also deals with the subsidence impact on surface and groundwater bodies, crucial resources that are often neglected by subsidence researchers.

TV portraits of the Miners' strike of 1984/5 stressed the violence of the pickets and responsible policing. This book challenges those images, looks at the impact of the strike on participants, and reflects on ongoing controversies and community pride.The book is organised into three parts. In early chapters participants look back. So, Peter Smith speaks of his honest determination not to become a 'professional sacked miner' and Sian James tells of her excitement and pride at her community's defence of a valued way of life. Political controversies are examined: Was the strike the result of careful planning (on the part of the Thatcher Government, and/or the NUM)? How and why were striking miners, at Orgreave in June 1984, injured, arrested and vilified? Why were miners determined not to be 'constitutionalized' or balloted out of their jobs? How did the BBC and ITV misrepresent police action and show miners as 'out of control'? Why did miners in Yorkshire, Nottinghamshire and elsewhere support, or oppose, the strike? The final section examines enduring issues especially the Orgreave Truth and Justice Campaign.Is a more critical assessment of Prime Minister Margaret Thatcher long overdue? Why is miners' history and heritage - as seen in the Durham Miners' Gala - so fondly celebrated?
