Recovery of Lithium from Secondary Resources: Recycling Technologies of Spent Lithium-Ion Batteries presents a state-of-the-art review of recent advances in the lithium recovery from spent lithium-ion batteries (LIBs). It examines the recovery of lithium from secondary sources and provides an introduction to the classification and structure of LIBs. It explains the development of LIBs for electric vehicles and addresses the potential impact of spent LIBs in the environment. Further, it also addresses the multiple treatment protocols for the recycling of LIBs and discusses the high value-added products from these processes. The book provides an essential resource for professionals, researchers, and policymakers in academia, industry, and governments around the globe.

Metallurgical slags are generated as a by-product of smelting during ironmaking, steelmaking, and the production of ferroalloys and non-ferrous metals. The formation conditions result in complex chemical and mineralogical characteristics unique to slags alone. Historically slags have been discarded as a waste product and, through release of potentially toxic trace elements, represent a hazard to the environment and human health. However, increasingly we are realizing the resource potential of what was previously thought of as waste, thus reducing the environmental impact and taking a step closer to a circular economy. This book is a definitive reference on the environmental geochemistry and resource potential of metallurgical slags by summarizing processes for the generation of slags, describing their chemical and mineralogical characteristics, outlining the fundamental geochemistry that propels slag weathering, and illustrating the utilization of slags. Particular attention is given to the value of slags in modern society as they are widely used as construction materials in civil engineering, and as an irreplaceable filter in sequestering excess nutrients, pathogens, metal and/or organic contaminants, and even greenhouse gases. The latest developments on recovering residual valuable metals in slags, including new techniques for extracting by-product elements needed for green and frontier technologies, are revealed. This book is essential reading for environmental geochemists, geologists, metallurgists, mining and civil engineers, waste and resource managers, and all those interested and inspired by a circular economy and minimizing our environmental footprint on planet Earth.

Resource recovery and recycling from millions of tons of wastes produced from industrial activities is a continuing challenge for environmental engineers and researchers. Demand for conservation of resources, reduction in the quantity of waste and sustainable development with environmental control has been growing in every part of the world. Waste Processing and Recycling in Mineral and Metallurgical Industries brings together the currently used techniques of waste processing and recycling, their applications with practical examples and economic potentials of the processes. Emphasis is on resource recovery by appropriate treatment and techniques. Material on the subject is scatterend in waste management and environmental related journals, conference volumes and government departmental technical reports. This work serves as a source book of information and as an educational technical reference for practicing scientists and engineers, as well as for students. * Describes the currently used and potential techniques for the recovery of valuable resources from mineral and metallurgical wastes * Discusses the applications to specific kinds of wastes with examples from current practices, as well as eht economics of the processes * Presents recent and emerging technologies of potentials in metal recycling and by-product utilization

This collection presents papers from a symposium on extraction of rare metals as well as rare extraction processing techniques used in metal production. Rare metals include strategic metals that are in increasing demand and subject to supply risks. Metals represented include neodymium, dysprosium, scandium and others; platinum group metals including platinum, palladium, iridium, and others; battery related metals including lithium, cobalt, nickel, and aluminum; electronics-related materials including copper and gold; and refectory metals including titanium, niobium, zirconium, and hafnium. Other critical materials such as gallium, germanium, indium and silicon are also included. Papers cover various processing techniques, including but not limited to hydrometallurgy (solvent extraction, ion exchange, precipitation, and crystallization), electrometallurgy (electrorefining and electrowinning), pyrometallurgy, and aeriometallurgy (supercritical fluid extraction). Contributions are focused on primary production as well as secondary production through urban mining and recycling to enable a circular economy. ​A useful resource for all involved in commodity metal production, irrespective of the major metal Provides knowledge of cross-application among industries Extraction and processing of rare metals that are the main building block of many emerging critical technologies have been receiving significant attention in recent years. The technologies that rely on critical metals are prominent worldwide, and finding a way to extract and supply them effectively is highly desirable and beneficial.

The preservation and careful management of the environment and of natural resources and recycling or the processing of used or abandoned materials for use in creating new products must become key parts of the equation for the Earth's continued sustainable development. At the present time, most developed countries are massively wasteful throughout almost all sectors of the economy ranging from energy use to consumer lifestyles. One of the main obstacles to conservation and recycling of resources is the lack in most countries of national mindsets encouraging such practices as well as the infrastructures to support their carrying out. This book presents important research in this frontal field.

Is Gaia becoming Thanatia, a resource exhausted planet? For how long can our high-tech society be sustained in the light of declining mineral ore grades, heavy dependence on un-recycled critical metals and accelerated material dispersion? These are all root causes of future disruptions that need to be addressed today. This book presents a cradle-to-cradle view of the Earth's abiotic resources through a novel and rigorous approach based on the Second Law of Thermodynamics: heat dissipates and materials deteriorate and disperse. Quality is irreversibly lost. This allows for the assessment of such depletion and can be used to estimate the year where production of the main mineral commodities could reach its zenith. By postulating Thanatia, one acquires a sense of destiny and a concern for a unified global management of the planet's abiotic resource endowment. The book covers the core aspects of geology, geochemistry, mining, metallurgy, economics, the environment, thermodynamics and thermochemistry. It is supported by comprehensive databases related to mineral resources, including detailed compositions of the Earth's layers, thermochemical properties of over 300 substances, historical energy and mineral resource inventories, energy consumption and environmental impacts in the mining and metallurgical sector and world recycling rates of commodities.

It is an essential read for any scientist who is concerned with resource evaluation and how we can best manage these assets and continue to live on an Earth in which we appreciate the service provided by the resource and thus avoid Thanatia in defence of Gaia." John Ludden Executive Director, British Geological Survey “'Thanatia' presents a refreshing way of analysing the run-down of our mineral inheritance … To serious students of the resource problem the numerous tables in 'Thanatia' are useful because they are thought-provoking as much as for the numerical data. 'Thanatia' is a big book, with a wealth of data and background material on the minerals industry, representing many years of intensive investigation and analysis.” Jane H Hodgkinson & Frank D Stacey CSIRO, Australia Authors of The Earth as a Cradle for Life “The unusual title of the book Thanatia (death in Greek) leads its readers to understand what sustainability really means and to quantify the problem of mineral depletion using both disciplines thermodynamics and economics. ” Ph.
