Download or read book Rare Earth Permanent Magnets written by I.R. Harris and published by Elsevier. This book was released on 2014-04-03 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: These papers provide an interesting collection of contributions on fundamental magnetic behaviour, microstructural studies, processing methods and applications of rare earth, iron-rich, high performance permanent magnets. The remarkably versatile nature of the Nd-Fe-B-type alloys with respect to magnet processing is very evident in these proceedings. Thus there are papers which describe the production of magnets by the die-upset-forging of melt-spun ribbon, by cold-compaction of melt-spun-ribbon with soft metals, by mechanical alloying and by hot working of cast material. Work is also reported on the production of new permanent magnets from melt-spun material based on the alloys Nd4Fe78B18 and SmFe11.5Ti1.04. Both these alloys look promising and the former appears to be close to commercial exploitation.

Book excerpt: Metal recycling is a complex business that is becoming increasingly difficult! Recycling started long ago, when people realized that it was more resource- and cost-efficient than just throwing away the resources and starting all over again. In this report, we discuss how to increase metal-recycling rates - and thus resource efficiency - from both quantity and quality viewpoints. The discussion is based on data about recycling input, and the technological infrastructure and worldwide economic realities of recycling. Decision-makers set increasingly ambitious targets for recycling, but far too much valuable metal today is lost because of the imperfect collection of end-of-life (EoL) products, improper practices, or structural deficiencies within the recycling chain, which hinder achieving our goals of high resource efficiency and resource security, and of better recycling rates.

Download or read book Handbook of Recycling written by Ernst Worrell and published by Newnes. This book was released on 2014-04-28 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the International Solid Waste Association's 2014 Publication Award, Handbook of Recycling is an authoritative review of the current state-of-the-art of recycling, reuse and reclamation processes commonly implemented today and how they interact with one another. The book addresses several material flows, including iron, steel, aluminum and other metals, pulp and paper, plastics, glass, construction materials, industrial by-products, and more. It also details various recycling technologies as well as recovery and collection techniques. To completely round out the picture of recycling, the book considers policy and economic implications, including the impact of recycling on energy use, sustainable development, and the environment. With contemporary recycling literature scattered across disparate, unconnected articles, this book is a crucial aid to students and researchers in a range of disciplines, from materials and environmental science to public policy studies. - Portrays recent and emerging technologies in metal recycling, by-product utilization and management of post-consumer waste - Uses life cycle analysis to show how to reclaim valuable resources from mineral and metallurgical wastes - Uses examples from current professional and industrial practice, with policy and economic implications

Available in PDF, EPUB and Kindle. Book excerpt: The Earth's natural resources are finite and easily compromised by contamination from industrial chemicals and byproducts from the degradation of consumer products. The growing field of green and sustainable chemistry seeks to address this through the development of products and processes that are environmentally benign while remaining economically viable. Inorganic chemistry plays a critical role in this endeavor in areas such as resource extraction and isolation, renewable energy, catalytic processes, waste minimization and avoidance, and renewable industrial feedstocks. Sustainable Inorganic Chemistry presents a comprehensive overview of the many new developments taking place in this rapidly expanding field, in articles that discuss fundamental concepts alongside cutting-edge developments and applications. The volume includes educational reviews from leading scientists on a broad range of topics including: inorganic resources, sustainable synthetic methods, alternative reaction conditions, heterogeneous catalysis, photocatalysis, sustainable nanomaterials, renewable and clean fuels, water treatment and remediation, waste valorization and life cycle sustainability assessment. The content from this book will be added online to the Encyclopedia of Inorganic and Bioinorganic Chemistry.

Download or read book Rare Metal Technology 2021 written by Gisele Azimi and published by Springer Nature. This book was released on 2021-02-16 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection presents papers from a symposium on extraction of rare metals as well as rare extraction processing techniques used in metal production. It covers metals essential for critical modern technologies including electronics, electric motors, generators, energy storage systems, and specialty alloys. Rare metals are the main building blocks of many emerging critical technologies and have been receiving significant attention in recent years. Much research in academia and industry is devoted to finding novel techniques to extract critical and rare metals from primary and secondary sources. The technologies that rely on critical metals are dominating the world, and finding a way to extract and supply them effectively is highly desirable and beneficial. Rapid development of these technologies entails fast advancement of the resource and processing industry for their building materials. Authors from academia and industry exchange knowledge on developing, operating, and advancing extractive and processing technologies. Contributions cover rare-earth elements (magnets, catalysts, phosphors, and others), energy storage materials (lithium, cobalt, vanadium, graphite), alloy elements (scandium, niobium, titanium), and materials for electronics (gallium, germanium, indium, gold, silver). The contributions also cover various processing techniques in mineral beneficiation, hydrometallurgy, separation and purification, pyrometallurgy, electrometallurgy, supercritical fluid extraction, and recycling (batteries, magnets, electrical and electronic equipment).
