Evolutionary and Revolutionary Technologies for Mining


Book Description

The Office of Industrial Technologies (OIT) of the U. S. Department of Energy commissioned the National Research Council (NRC) to undertake a study on required technologies for the Mining Industries of the Future Program to complement information provided to the program by the National Mining Association. Subsequently, the National Institute for Occupational Safety and Health also became a sponsor of this study, and the Statement of Task was expanded to include health and safety. 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.

Surface Mining Machines


Book Description

This unique volume imparts practical information on the operation, maintenance, and modernization of heavy performance machines such as lignite mine machines, bucket wheel excavators, and spreaders. Problems of large scale machines (mega machines) are highly specific and not well recognized in the common mechanical engineering environment. Prof. Rusiński and his co-authors identify solutions that increase the durability of these machines as well as discuss methods of failure analysis and technical condition assessment procedures. "Surface Mining Machines: Problems in Maintenance and Modernization" stands as a much-needed guidebook for engineers facing the particular challenges of heavy performance machines and offers a distinct and interesting demonstration of scale-up issues for researchers and scientists from across the fields of machine design and mechanical engineering.

Halogenated Hydrocarbons and Alcohols


Book Description

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.

Comprehensive Hard Materials


Book Description

Comprehensive Hard Materials, Three Volume Set deals with the production, uses and properties of the carbides, nitrides and borides of these metals and those of titanium, as well as tools of ceramics, the superhard boron nitrides and diamond and related compounds. Articles include the technologies of powder production (including their precursor materials), milling, granulation, cold and hot compaction, sintering, hot isostatic pressing, hot-pressing, injection moulding, as well as on the coating technologies for refractory metals, hard metals and hard materials. The characterization, testing, quality assurance and applications are also covered. Comprehensive Hard Materials provides meaningful insights on materials at the leading edge of technology. It aids continued research and development of these materials and as such it is a critical information resource to academics and industry professionals facing the technological challenges of the future. Hard materials operate at the leading edge of technology, and continued research and development of such materials is critical to meet the technological challenges of the future. Users of this work can improve their knowledge of basic principles and gain a better understanding of process/structure/property relationships. With the convergence of nanotechnology, coating techniques, and functionally graded materials to the cognitive science of cemented carbides, cermets, advanced ceramics, super-hard materials and composites, it is evident that the full potential of this class of materials is far from exhausted. This work unites these important areas of research and will provide useful insights to users through its extensive cross-referencing and thematic presentation. To link academic to industrial usage of hard materials and vice versa, this work deals with the production, uses and properties of the carbides, nitrides and borides of these metals and those of titanium, as well as tools of ceramics, the superhard boron nitrides and diamond and related compounds.
