Download or read book On Borrowed Time written by John E. Tilton and published by Routledge. This book was released on 2010-09-30 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sharp rise in mineral use has revived concern about scarcity. Economist John Tilton responds by analyzing recent trends in the consumption and availability of minerals that are most integral to the needs of modern civilization. He reminds readers that, if the arguments about scarcity sound familiar, it is because the story of minerals scarcity is almost as old as human history-and so too is substitution and technological innovation. The issue at hand is the unprecedented acceleration in exploitation and use. Given global population growth, rising living standards, and environmental concerns, how seriously should today‘s society take the threat of mineral exhaustion? On Borrowed Time? provides general interest and student readers with an accessible framework for understanding scarcity. Tilton defines important concepts and explores the methods used to study mineral scarcity, including physical measures of known reserves and the total resource base, and economic measures, such as extraction and end-user costs. He notes the increasing emphasis on the social and environmental costs of mineral production and use, placing the scarcity debate in context of broader concerns about sustainability and equity. He adds a history of thought about scarcity, from Malthus and Ricardo to Harold Hotelling, Donella Meadows, to the present day.
Download or read book Current Trends in Geomathematics written by Daniel Merriam and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since founding at the 23rd International Geological Congress in Prague in 1968, the International Association for Mathematical Geology has organized sessions in conjunction with the Congress. The 27th IGC in Moscow was no exception and the IAMG again held sessions and assisted the Congress in organizing Section 20 -Mathematical Geology and Geological Information ( D. F. Merriam, D. A. Rodionov, and R. Sinding-Larsen, conveners). All together 128 abstracts were published in the technical proceedings. Several of the papers were published prior to the Congress, others were not available, and others deemed not appropriate for publication in this volume. This collection then contains those papers aVailable and representative of the sessions. The collection is truly international with contributions from Canada, China, France, Poland, the UK, USA, and USSR. They are representative of the state-of-the-art as of the early 1980s in a variety of fields. The application of geomathematics/geostatistics to geological problems has been hastened by the availability of computers. These papers reflect that orientation -most of the results would not have been possible without the use of computers. Most of the approaches utilize techniques readily aVailable and adapted to solving geological problems -simulation, image analysis, decision theory, fuzzy sets, etc. However, one area, that of geostatistiques which includes Kriging, has been designed especially for use by earth scientists of the French school to solve geological problems.
Download or read book Surface Mining Second Edition written by Bruce A. Kennedy and published by SME. This book was released on 1990 with total page 1214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SME classic is both a reference book for the working engineer and a textbook for the mining student. This hardcover edition gives a brief history of surface mining and a general overview of the state of surface mining today--topics range from production and productivity to technological developments and trends in equipment. This extremely useful text takes the approach that exploration and mining geologists must be expert in a number of fields, including basic finance and economics, logistics, and pragmatic prospecting. Readers will find material on all these topics and more. The book's nine chapters include: Introduction, Exploration and Geology Techniques, Ore Reserve Estimation, Feasibility Studies and Project Financing, Planning and Design of Surface Mines, Mine Operations, Mine Capital and Operating Costs, Management and Organization, and Case Studies. The book is fully indexed.

Available in PDF, EPUB and Kindle. Book excerpt: World Mineral Supplies: Assessment and Perspective examines some of the issues in the debate about whether there is an impending global shortage of mineral resources and whether technology and exploration can meet the needs of a rapidly growing rate of mineral consumption in the world. The geologic and economic factors that determine the demand for and the availability and distribution of mineral resources and reserves are discussed, and the future of mineral resource supplies is considered. Comprised of 14 chapters, this volume places emphasis on the technical problems of assuring adequate mineral supplies for the future. The discussion begins by analyzing the complexities and confusion that color much of the discussion about the size and adequacy of world mineral supplies, focusing on the importance of distinguishing between "resources" and "reserves". The next chapter deals with the creation of reserves from resources as a function of price, cost, ore grade, and technology. Subsequent chapters explore the physical and chemical factors that determine the absolute abundance and the actual availability and distribution of resources; the actual geographic distribution among countries of mineral supply and demand; and trends in energy consumption and supply. Conservation of minerals and of the environment and mineral exploration and technical cooperation in developing countries are also treated in considerable detail, along with deep mining techniques and UNDP-assisted projects in geology and mineral resources. This book will be of interest to economists, social scientists, geologists, mining engineers, and mineral technologists.
Download or read book Mineral Materials Modeling written by William A. Vogely and published by Routledge. This book was released on 2015-09-16 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1976, this study was undertaken to fill a gap in knowledge about non-fuel resources and the advantages and disadvantages of specific methodologies of analysing material modelling. Mineral Materials Modeling examines the influence of factors such as raw material price and availability, technological aspects and related environmental questions in relation to both economic and mathematical models. The results are particularly helpful in terms of forecasting, policy development and decision-making about mineral materials as well as assessing the usefulness of different types of model. This title will be of interest to students of Environmental Studies as well as policy makers and professionals.
Download or read book Copper Availability Domestic written by Rodney D. Rosenkranz and published by . This book was released on 1979 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bureau of Mines evaluated the potential supply of primary copper from domestic mines and deposits and found that increases in copper price will be required in order for many domestic deposits to continue production. As part of the study, a tonnage-price relationship was developed indicating the quantity of copper that could be produced economically from known deposits at various copper prices and at various rates of return on the required capital investment. Costs of production are based on estimated capital and operating costs for mining, concentrating, transporting, smelting, and refining. Direct and indirect operating costs, recovery of investment, and return on investment have been included in the smelting and refining costs. Capital and operating costs are calculated in January 1978 dollars, and byproduct credits are based on January 1978 prices. Known domestic copper mines and deposits contain nearly 92 million metric tons of copper in about 14 billion metric tons of demonstrated mineralized material. These tonnages represent the current domestic copper reserve base. Approximately 74 million metric tons of copper are recoverable from the reserve base using existing technology. Of this quantity, slightly more than 50 million metric tons are economically recoverable assuming a price of 51.00 per pound of copper, credit for the recovery of byproducts, and a 15-percent rate of return on capital investment. Approximately 60 percent of the copper occurs in mines that were producing at the time of the study.
