The overall objectives of this study are: (a) to review available information on the U.S. mining industry; (b) to identify critical research and development needs related to the exploration, mining, and processing of coal, minerals, and metals; and (c) to examine the federal contribution to research and development in mining processes.




Basics of Metal Mining Influenced Water


Book Description

Basics of Metal Mining Influenced Water is a must-read for planners, regulators, consultants, land managers, students, researchers, or others concerned about the environmentally sound management of metal mine wastes and drainage quality. The first of a series of six handbooks on technologies for managing metal mine and metallurgical process draining, this book offers a unique, comprehensive perspective on the subject. Unlike other texts that focus primarily on acid drainage from coal mines, the authors examine both acidic and neutral pH waters that can be hazardous to the environment. Planning a new mine in today s increasingly contentious regulatory and political environment demands a different philosophy. Basics of Metal Mining Influenced Water takes an innovative, holistic approach by considering all aspects of the mine life cycle, including closure. Written by a team of experts from state and federal governments, academia, and the mining industry, Basics of Metal Mining Influenced Water also discusses the major physical and chemical relationships between mining, climate, environment, and mine waste drainage quality. The authors have included an extensive glossary defining hundreds of technical terms for easier reading and understanding.




Early Metal Mining and Production


Book Description

Technical advancement has for millennia been intimately linked to the mining and production of metals, and this book provides a comprehensive history of the early development of extractive metallurgy. Drawing on the latest archaeological discoveries and laboratory investigations, Paul Craddock brings together for the first time the evidence for the very inception of mining and smelting, showing that early techniques were often different from what was previously believed. The book presents much new material throughout and provides new interpretations and insights into many aspects of early metal production right through to the blast furnaces and high-temperature distillation units that heralded the Industrial Revolution. Integrating documentary evidence with metallurgical study and new information from archaeological excavations in Europe, India, North America, and China, this book gives a full and approachable synthesis of mining and metal production everywhere.




Applied Mineralogy in the Mining Industry


Book Description

Techniques of performing applied mineralogy investigations, and applications and capabilities of recently developed instruments for measuring mineral properties are explored in this book intended for practicing applied mineralogists, students in mineralogy and metallurgy, and mineral processing engineers. The benefits of applied mineralogy are presented by using in-depth applied mineralogy studies on base metal ores, gold ores, porphyry copper ores, iron ores and industrial minerals as examples. The chapter on base metal ores includes a discussion on the effects of liberation, particle sizes and surfaces coatings of Pb, Cu, Fe, Ca and So4- on the recoveries of sphalerite, galena and chalcopyrite. The chapter on gold discusses various methods of determining the quantities of gold in different minerals, including 'invisible' gold in pyrite and arsenopyrite, so that a balance of the distribution of gold among the minerals can be calculated. This book also discusses the roles of pyrite, oxygen, moisture and bacterial (thiobacillus ferrooxidans) on reactions that produce acidic drainage from tailings piles, and summarizes currently used and proposed methods of remediation of acidic drainage.




Mining Economics and Strategy


Book Description

This book will help direct mining operations through the use of innovative economic strategies. The text covers what is meant by a cost-effective mining scheme, the economics of information, and the procedures for rational evaluation of uncertain projects.




Mining and the Environment


Book Description

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.




Ores to Metals


Book Description

This comprehensive treatment of the smelting industry of Colorado, originally published in 1979, is now back in print with a new preface by the author. Packed with fascinating statistics and mining data, Ores to Metals details the people, technologies, and business decisions that have shaped the smelting industry in the Rockies. Although mining holds more of the glamour for those in and interested in the minerals industry, smelters have continuously played a critical role in the industry’s evolution since their introduction in Colorado in the 1860s. At that time, miners desperately needed new technology to recover gold and silver from ores resistant to milling. Beginning as small independent enterprises, progressing to larger integrated firms working in urban centers, and finally following a trend toward mergers, the entire industry was absorbed into one large holding company—the American Smelting and Refining Company. Over time, fortunes were won and lost, business success was converted to political success, and advances were made in science and metallurgy. Drawing on archival material, Fell expertly presents the triumphs and troubles of the entrepreneurs who built one of the great industries of the West.




Mining and Sustainable Development


Book Description

Mining is a transformative activity which has numerous economic, social and environmental impacts. These impacts can be both positive and adverse, enhancing as well as disrupting economies, ecosystems and communities. The extractive industries have been criticised heavily for their adverse impacts and involvement in significant social and environmental scandals. More recently, these industries have sought to respond to negative perceptions and have embraced the core principles of sustainability. This sector could be regarded as a leader in sustainability initiatives, evident from the various developments and frameworks in mining and sustainability that have emerged over time. This book reviews current topical issues in mining and sustainable development. It addresses the changing role of minerals in society, the social acceptance of mining, due diligence in the mining industry, critical and contemporary debates such as mining and indigenous peoples and transit worker accommodation, corporate sustainability matters such as sustainability reporting and taxation, and sustainability solutions through an emphasis on renewable energy and shared-used infrastructure. Written by experts from Australia, Europe and North America, but including examples from both developed and developing countries, the chapters provide a contemporary understanding of sustainability opportunities and challenges in the mining industry. The book will be of interest to practitioners, government and civil society as well as scholars and students with interests in mining and sustainable development.
