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.

Metal Value Recovery from Industrial Waste Using Advanced Physicochemical Treatment Technologies focuses on the fundamental and advanced topics involved with the technologies for the extraction of metal ions from different industrial discarded volumes which may be sludge or wastewater. Uniqueness of the book lies in the fact that it covers each topic related to industrial wastes and elaborates on discussions on metal ion recovery to make the readers confident about the topics and concepts explained in the section. Moreover, this book examines high potential in different downstream processes like membrane filtration, hybrid techniques, chemical leaching, electrochemical techniques, and a variety of advanced recovery techniques. Emphasis is given to state-of-the-art concept, latest research, practical applications or commercialization through case studies, and comparative evaluation of the processes for metal ion recovery from industrial wastes. - Provides updated occurrence and characteristics of a variety of high valued metal ions different industrial wastes - Presents a detailed account of advanced chemical leaching technologies for the recovery of those metal ions - Covers innovative approaches for the reutilization and management of industrial wastes in a very easily understandable way with visual elements so that the knowledge can reach out to all interested learners - Describes specific metal recovery will contain the case-studies (wherever applicable) to describe the lab to pilot scale to the industrial scale implementation

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.

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.
