Download and read online Introductory Mining Engineering in PDF and EPUB Hartman (mining engineering, U. of Alabama) and Mutmansky (emeritus, mining engineering, Pennsylvania State U. at University Park) have two primary aims in the presentation of the second edition of their mining textbook: to familiarize readers with the minerals industry and to aid in the selection of the optimal methods for the specified conditions. To achieve those goals they present 14 chapters covering mining and its consequences, prospecting and exploration, development and exploitation, unit operations of mining, surface mine development, mechanical extraction methods, aqueous extraction methods, underground mine development, unsupported and supported methods in underground mining, caving methods, and novel methods and technology.

Download and read online Eagle Picher Industries in PDF and EPUB This comprehensive history traces the evolution of Eagle-Picher Industries, a manufacturing firm based in Cincinnati, Ohio, for almost 150 years. Focusing on events prior to the company's involvement in toxic tort litigation, which forced it to file bankruptcy, this work examines Eagle-Picher's development as a diversified industrial manufacturer. From a closely held, regional producer of white lead and other paint pigments, Eagle-Picher became an important miner and processor of non-ferrous metals by investing in zinc-lead fields in Missouri, Kansas, and Oklahoma during the early twentieth century. Once ore reserves in these areas were depleted, the company turned to manufacturing industrial goods and pursued an aggressive and unique expansion and diversification program during the post-World War II era. During the 1950s, 1960s, and 1970s, Eagle-Picher acquired over twenty-five firms, all manufacturers of industrial goods, and assembled a broadly based specialized productive capacity. Eagle-Picher's history illustrates a number of important trends and concepts. First, its experiences in the late nineteenth century provide a valuable look at how smaller firms adapted to the forces of consolidation in the economy. Further, Eagle-Picher's experience as an industrial manufacturer demonstrates the ways in which mid-sized firms grew by focusing on market niches overlooked by larger firms. Finally, Eagle-Picher's approach to acquisition and diversification is unique in today's competitive marketplace. Eagle-Picher's commitment to limited diversification built around historical strengths, its acquisition of successful firms, and its efforts to establish strong lines of communication and effective controls between the central office and the divisions stand in stark contrast to the efforts of many acquisitive firms during recent mergers.

Download and read online Using the Engineering Literature Second Edition in PDF and EPUB With the encroachment of the Internet into nearly all aspects of work and life, it seems as though information is everywhere. However, there is information and then there is correct, appropriate, and timely information. While we might love being able to turn to Wikipedia® for encyclopedia-like information or search Google® for the thousands of links on a topic, engineers need the best information, information that is evaluated, up-to-date, and complete. Accurate, vetted information is necessary when building new skyscrapers or developing new prosthetics for returning military veterans While the award-winning first edition of Using the Engineering Literature used a roadmap analogy, we now need a three-dimensional analysis reflecting the complex and dynamic nature of research in the information age. Using the Engineering Literature, Second Edition provides a guide to the wide range of resources available in all fields of engineering. This second edition has been thoroughly revised and features new sections on nanotechnology as well as green engineering. The information age has greatly impacted the way engineers find information. Engineers have an effect, directly and indirectly, on almost all aspects of our lives, and it is vital that they find the right information at the right time to create better products and processes. Comprehensive and up to date, with expert chapter authors, this book fills a gap in the literature, providing critical information in a user-friendly format.
Download and read online Minerals Yearbook V 3 Area Reports International Review in PDF and EPUB The Minerals Yearbook is an annual publication that reviews the mineral and material industries of the United States and foreign countries. The Yearbook contains statistical data on materials and minerals and includes information on economic and technical trends and development. The Minerals Yearbook includes chapters on approximately 90 commodities and over 175 countries. This volume of the Minerals Yearbook provides an annual review of mineral production and trade and of mineral-related government and industry developments in more than 175 foreign countries. Each report includes sections on government policies and programs, environmental issues, trade and production data, industry structure and ownership, commodity sector developments, infrastructure, and a summary outlook.
Download and read online Recent Advances in Mining and Processing of Low Grade and Submarginal Mineral Deposits in PDF and EPUB Recent Advances in Mining and Processing of Low-Grade and Submarginal Mineral Deposits reviews advances in the mining and processing of low-grade and submarginal mineral deposits, taking into account the environmental considerations that increasingly are being regarded as a necessary prerequisite to acceptable mineral resources development. The focus is on marginal and sub-marginal ores, as well as ores of above normal cut-off grades which for some reason cannot be mined and/or processed economically at current technological or economic levels. This book is comprised of 12 chapters and begins with an overview of low-grade ore potential, followed by a discussion on the theoretical and practical aspects of in situ mining. Block cave-in place leaching, biological leaching of sulfide ores, and nuclear chemical mining of primary copper sulfides are also considered. Subsequent chapters explore the economics and safety of nuclear chemical copper mining; hydrometallurgy of low-grade copper ores; trends in process metallurgy; and environmental aspects of mining and processing low-grade and submarginal mineral deposits. This monograph should be of interest to mining officials and professionals.

Download and read online Mining archaeology in the American West in PDF and EPUB Mining played a prominent role in the shaping and settling of the American West in the nineteenth century. Following the discovery of the famous Comstock Lode in Nevada in 1859, mining became increasingly industrialized, changing mining technology, society, and culture throughout the world. In the wake of these changes, Nevada became an important mining region, with new people and technologies further altering the ways mining was pursued and miners interacted. Historical archaeology offers a research strategy for understanding mining and miners that integrates three independent sources of information about the past: physical remains, documents, and oral testimony. Mining Archaeology in the American West explores mining culture and practices through the microcosm of Nevada’s mining frontier. The history of mining technology, the social and cultural history of miners and mining societies, and the landscapes and environments of mining are topics examined in this multifocus research. In this updated and expanded edition of the seminal work on mining in Nevada, Donald Hardesty brings scholarship up to the present with important new research and insights into how people, technology, culture, architecture, and landscape changed during this period of mining history.
Download and read online Around Terlingua in PDF and EPUB The origin of the name “Terlingua” is obscure and lost in time. For the past century and a half, the area covered by the name has expanded to include numerous concentrations of people engaged to varying degrees in ranching, farming, and mining, or the support thereof. Farmers and ranchers produced agricultural products, woodcutters supplied timbers for the mines or fuel for the furnaces, and storekeepers supplied the goods needed for sustenance of this diverse community that was spread over much of south Brewster County in West Texas. Hispanic people who began settling the region in the 18th century were the backbone of the mining industry. Many of the families here today are descendants of the mine workers and continue contributing to the community. This story tells of the establishment and abandonment of Terlingua following the rise and decline in demand for mercury and how the ghost town was resurrected in the 20th century.
