Book Description
This comprehensive textbook covers all major topics related to the utilization of mineral resources for human activities. It begins with general concepts like definitions of mineral resources, mineral resources and humans, recycling mineral resources, distribution of minerals resources across Earth, and international standards in mining, among others. Then it turns to a classification of mineral resources, covering the main types from a geological standpoint. The exploration of mineral resources is also treated, including geophysical methods of exploration, borehole geophysical logging, geochemical methods, drilling methods, and mineral deposit models in exploration. Further, the book addresses the evaluation of mineral resources, from sampling techniques to the economic evaluation of mining projects (i.e. types and density of sampling, mean grade definition and calculation, Sichel’s estimator, evaluation methods – classical and geostatistical, economic evaluation – NPV, IRR, and PP, estimation of risk, and software for evaluating mineral resources). It subsequently describes key mineral resource exploitation methods (open pit and underground mining) and the mineral processing required to obtain saleable products (crushing, grinding, sizing, ore separation, and concentrate dewatering, also with some text devoted to tailings dams). Lastly, the book discusses the environmental impact of mining, covering all the aspects of this very important topic, from the description of diverse impacts to the environmental impact assessment (EIA), which is essential in modern mining projects.

Book Description
As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.

Book Description
Dissipative flows of mineral resources are central to environmental impact assessment, since they are harmful to the environment and embody a wasteful use of non-renewable resources. Life Cycle Assessment (LCA) is a recognized environmental assessment tool framed by the ISO 14040/44 norms, typically aiming to prevent damage on three areas of protection (AoP): ecosystem health, human health, and natural resources.Traditionally, the depletion of mineral resources has been assessed to quantify impacts on the AoP natural resources. However, recent trends in discussion within the LCA community suggest that dissipation of minerals may be more relevant to assess, since they represent the real loss of materials that are no longer accessible for future use, whereas the depletion of geological stocks may actually be considered to be desirable for as long as mineral resources remain accessible for further human use.This thesis has the objective to improve the consideration of dissipative flows of mineral resources in the LCA framework, focusing on the AoP natural resources. Broadly speaking, two topics are encompassed within the objective: improving the understanding of the impacts of mineral resource use on the AoP natural resources, and developing a life cycle impact assessment (LCIA) method allowing to quantify these impacts in relation to the dissipation of mineral resources.We first investigate the impact pathways relating human interventions to the AoP natural resources. The relation between resource flows and the AoP natural resources is studied in order to provide a coherent framework to assess the impacts of mineral resource use on the AoP using multiple LCIA methods at once. Then, we explore concepts and terminology surrounding dissipation and propose a conceptual framework to address the dissipation of mineral resources based on dynamic material flow analysis (MFA) data. Two options are identified: reworking current life cycle inventories to integrate dissipative flows and develop a life cycle impact assessment (LCIA) method accordingly, or propose a LCIA method that integrates dissipation in the calculation of its characterization factors that can be applied to extraction flows in the current inventories. The second option is further developed in this thesis.In order to develop LCIA methods, data is collected for 61 metallic elements and dynamic material flow analysis results are computed for them. We then propose two methods to measure the impact of dissipation on mineral resources: the average dissipation rate (ADR) and the potential service time lost (LPST). Based on the dynamic material flow analysis results, midpoint characterization factors are calculated for 61 metals. In addition, endpoint characterization factors are computed using a price-based index. Finally, the characterization factors are applied to a wide range of life cycle inventory datasets in order to observe the trends to be expected in LCA studies covering the dissipation of mineral resources using the developed methods. These results are compared to those of other frequently used LCIA methods to address the impacts of mineral resource use.

Book Description
Minerals are part of virtually every product we use. Common examples include copper used in electrical wiring and titanium used to make airplane frames and paint pigments. The Information Age has ushered in a number of new mineral uses in a number of products including cell phones (e.g., tantalum) and liquid crystal displays (e.g., indium). For some minerals, such as the platinum group metals used to make cataytic converters in cars, there is no substitute. If the supply of any given mineral were to become restricted, consumers and sectors of the U.S. economy could be significantly affected. Risks to minerals supplies can include a sudden increase in demand or the possibility that natural ores can be exhausted or become too difficult to extract. Minerals are more vulnerable to supply restrictions if they come from a limited number of mines, mining companies, or nations. Baseline information on minerals is currently collected at the federal level, but no established methodology has existed to identify potentially critical minerals. This book develops such a methodology and suggests an enhanced federal initiative to collect and analyze the additional data needed to support this type of tool.

Book Description
Mineral resource estimation has changed considerably in the past 25 years: geostatistical techniques have become commonplace and continue to evolve; computational horsepower has revolutionized all facets of numerical modeling; mining and processing operations are often larger; and uncertainty quantification is becoming standard practice. Recent books focus on historical methods or details of geostatistical theory. So there is a growing need to collect and synthesize the practice of modern mineral resource estimation into a book for undergraduate students, beginning graduate students, and young geologists and engineers. It is especially fruitful that this book is written by authors with years of relevant experience performing mineral resource estimation and with years of relevant teaching experience. This comprehensive textbook and reference fills this need.

Book Description
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.

Book Description
Information about reserves of mineral deposits is essential for developing government policies on resources and land use. The U.S. Geological Survey (USGS) is the main government information source on domestic mineral resources. The Bureau of Land Management (BLM) and the Forest Service, the two largest federal land managing agencies, expect to spend about $200 million preparing their land use plans through fiscal year 1986. Unless USGS programs are accelerated, many of these plans will not be able to incorporate USGS information on possible mineral resources on federal lands, and additional costs could be incurred if revisions to the plans are necessary. USGS programs could: (1) help Congress decide which federal lands should be established as wilderness areas; (2) supply information important in carrying out a potential leasing program for mining nonfuel minerals on federal lands; and (3) benefit the domestic mining industry. The following shortcomings should be corrected: (1) USGS lacks a structured, formal plan for completing its mineral resource assessment; (2) USGS has not consulted federal and state land managing agencies or the mining industry to determine their information needs; (3) USGS could benefit from establishing a committee of leading experts who have a direct interest in the mineral industry; and (4) more coordination is needed in land use planning schedules and mineral assessment schedules. USGS did not always have adequate scientific expertise to work on the programs.
