Minerals, Metals and Sustainability examines the exploitation of minerals and mineral products and the implications for sustainability of the consumption of finite mineral resources and the wastes associated with their production and use. It provides a multi-disciplinary approach that integrates the physical and earth sciences with the social sciences, ecology and economics. Increasingly, graduates in the minerals industry and related sectors will not only require a deep technical and scientific understanding of their fields (such as geology, mining, metallurgy), but will also need a knowledge of how their industry relates to and can contribute to the transition to sustainability. Chapters 1 to 3 introduce the concept of materials, how they are used in society and the environmental basis of our existence. Chapter 4 introduces the concept of sustainability and the issues it raises for the use of non-renewable resources. Chapter 5 discusses the geological basis of the minerals industry and Chapter 6 describes the structure and nature of the industry. Chapters 7 and 8 review the technologies by which mineral resources are extracted from the Earth’s crust and processed. Chapters 9 and 10 examine the usage of energy and water. Chapters 11 and 12 survey the wastes resulting from the production of mineral and metal commodities, the human and environmental impacts of these, and how they are managed. Chapter 13 examines the recycling of mineral-derived materials and the role of secondary materials in meeting material needs. Chapter 14 surveys the potential future sources of minerals and the factors that determine long-term supply. Chapter 15 surveys the socio-economic and technological factors that determine the long-term demand for mineral-derived materials and future trends. Chapter 16 discusses how waste can be reduced, or eliminated, through technological developments and socio-political changes. Finally, Chapter 17 addresses the concept of stewardship and the role the minerals industry should play in the ongoing transition to sustainability. Minerals, Metals and Sustainability is an important reference for students of engineering and applied science and geology; practising engineers, geologists and scientists; students of economics, social sciences and related disciplines; professionals in government service in areas such as resources, environment and sustainability; and non-technical professionals working in the minerals industry or in sectors servicing the minerals industry.

The sustainable use of natural resources is an important global challenge, and improved metal sustainability is a crucial goal for the 21st century in order to conserve the supply of critical metals and mitigate the environmental and health issues resulting from unrecovered metals. Metal Sustainability: Global Challenges, Consequences and Prospects discusses important topics and challenges associated with sustainability in metal life cycles, from mining ore to beneficiation processes, to product manufacture, to recovery from end-of-life materials, to environmental and health concerns resulting from generated waste. The broad perspective presented highlights the global interdependence of the many stages of metal life cycles. Economic issues are emphasized and relevant environmental, health, political, industrial and societal issues are discussed. The importance of applying green chemistry principles to metal sustainability is emphasized. Topics covered include: • Recycling and sustainable utilization of precious and specialty metals • Formal and informal recycling from electronic and other high-tech wastes • Global management of electronic wastes • Metal reuse and recycling in developing countries • Effects of toxic and other metal releases on the environment and human health • Effect on bacteria of toxic metal release • Selective recovery of platinum group metals and rare earth metals • Metal sustainability from a manufacturing perspective • Economic perspectives on sustainability, mineral development, and metal life cycles • Closing the Loop – Minerals Industry Issues The aim of this book is to improve awareness of the increasingly important role metals play in our high-tech society, the need to conserve our metal supply throughout the metal life cycle, the importance of improved metal recycling, and the effects that unhindered metal loss can have on the environment and on human health.

This book is a must for individuals and companies that have an interest in developing sustainable technology and systems in the complex 'Web of Metals' on a first principles, technological and economic basis, with a focus to the minerals, metals and product manufacturing industries. In this inter-, intra- and trans-disciplinary book the material/metal cycle will be central, addressing technology as the basis for achieving sustainability within the system of primary mineral and metal producing, and the consumer product material cycles, linked to nature's cycles. The following major topics (not exclusive) are discussed in a detail, which will satisfy company CEO's and students of environment, engineering, economics, and law alike: (i) industrial ecology, (ii) system engineering concepts, (iii) development of future breakthrough technology as well optimization of present technology, (iv) process fundamentals (e.g. thermodynamics, separation physics, transport processes etc.), (v) product manufacture and design (for recycling), (vi) environmental legislation and (vii) technology as a basis for achieving sustainability within our present society. The book discusses contentious issues such as the limits of recycling determined by physics, chemistry, economics and process technology, therefore providing the reader with a fundamental basis to understand and critically discuss the validity of environmental legislation. Furthermore, the 'Web of Metals' (i.e. the dynamic interconnection of metal and material cycles and product systems) will reveal that, if the application of environmental evaluation techniques such as material flow analysis, life cycle assessment etc. are not carried out on a sufficient theoretical basis, technological and economic understanding, analyses could lead to erroneous and in the end environmentally harmful conclusions. The book is illustrated with many industrial examples embracing car and electronic consumer goods manufacturing and recycling, and the production and recycling of all major metals (e.g. steel, aluminium, copper, zinc, lead, magnesium, PGM's and PM's) and to an extent plastics. A complete section of the book is devoted to the recycling of light metals. Numerous colour figures and photos, plant and reactor data as well as software and computer models (running under Matlab's Simulink® and AMPL® as well as tools based on neural net technology (CSenseTM) are provided to give the reader the opportunity to investigate the various topics addressed in this book at various levels of depth and theoretical sophistication, providing a wealth of information, share-data and industrial know-how. Finally, the book philosophically discusses how to harmonize the resource, life and technological cycles depicted by the figure on the cover to make a contribution to the sustainable use of resources and products. * Material and Metal Ecology and the various modelling aspects to quantify this * System modelling of recycling systems with applications in the automotive and consumergoods sector* Metallurgical metal recycling with applications in aluminium, supplemented with various modelling examples from thermodynamics, exergy, neural nets to CFD

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.
