New discoveries of the properties of gold at a nanoscale, and its effective use in modern technologies, have been driving a virtual 'gold rush'. Depleting natural resources has meant that the recovery of gold continues to grow in importance and relevance.The Recovery of Gold from Secondary Sources analyses the most advanced technology in gold recovery and recycling from spent sources of mobile phones, unwanted electronic equipment and waste materials. State-of-the-art techniques of hydrometallurgical and bio-metallurgical processing, leaching, cementing, adsorbing and separation through bio-sorbents are all described in detail, providing a guide for students and researchers. Discussion of environmentally friendly methods of recovery are presented, in order to provide modern-day alternatives to previous techniques. For those interested in the study of gold recovery this book gives a comprehensive overview of current recovery, making it the ultimate source of information for students, researchers, chemists, metallurgists, environmental scientists and electronic waste recovery experts.

The main impression of this book is to draw attention to the most advance technologies in silver recovery and recycling from various sources. The state-of-the-art in silver recovery from different sources by hydrometallurgical and bio-metallurgical processing, and varieties of leaching, cementing, reducing agents, peeling, electro-coagulants, adsorbents, electro-dialysis, solvent extraction, ion exchange resins and bio-sorbents are highlighted in this book. It is shown that the major economic driver for the recycling of depleted sources is for the recovery of silver. In order to develop a nature-friendly technique for the recovery of silver from diverse sources, a critical comparison of existing technologies is analysed for both economic viability and environmental impact were made in this amendment, and silver ion toxicity is highlighted in this book. This book comprises four chapters, each of which is further divided into sections and subsections for the proper convenience and understanding of the work, though extensive work has been reported on silver hydrometallurgy.

Electronic Waste Management and Treatment Technology applies the latest research for designing waste treatment and disposal strategies. Written for researchers who are exploring this emerging topic, the book begins with a short, but rigorous, discussion of electric waste management that outlines common hazardous materials. such as mercury, lead, silver and flame-retardants. The book also discusses the fate of metals contained in waste electrical and electronic equipment in municipal waste treatment. Materials and methods for the remediation, recycling and treatment of plastic waste collected from waste electrical and electronic equipment (WEEE) are also covered. Finally, the book covers the depollution benchmarks for capacitors, batteries and printed circuit boards from waste electrical and electronic equipment (WEEE) and the recovery of waste printed circuit boards through pyrometallurgy. - Describes depollution benchmarks for capacitors, batteries and printed wiring boards from waste electronics - Covers metals contained in waste electrical and electronic equipment in municipal waste - Provides tactics for the recycling of mixed plastic waste from electrical and electronic equipment

Currently, recycling of e-waste can be broadly divided into three major steps: (a) disassembly: selectively disassembly, targeting on singling out hazardous or valuable components for special treatment, is an indispensable process in recycling of e-waste; (b) upgrading: using mechanical processing and/or metallurgical processing to up-grade desirable materials content, i.e. preparing materials for refining process, such as grinding the plastics into powders; (c) refining: in the last step, recovered materials are retreated or purified by using metallurgical processing so as to be acceptable for their original using. Four topical areas are planned including one special session on the recycling of batteries. Papers in the following topics will be welcomed: Mechanical recycling of E-Wastes Recycling of plastics from E-Wastes Recovery of metals from E-wastes Hydrometallurgical recycling (leaching) of E-Wastes Combustion or pyrolysis of E-Wastes Life cycle and economic analysis for the recycling of E-Wastes
